    I know that is something that needs to be checked. Getting the hub off the crank looks like a real PITA. I am "hoping" that the crank balancer being off 180 degrees is evidence that it might have already been changed.

    Do you think this set of seat belts from a 69 Camaro would work (minus the retractors) for my 70 Deville? I already have the retractors, so possibly I could use the remaining pieces of the set. This set on eBay is not in great shape, but at least want to know if it is an option.

    I think it would work. Did you have any luck with the used parts guys in Arizona? Email Kristi Brake <azcadillacparts555@gmail.com> see if they can help you.

    Re: New Owner Red 1970 Cadillac Deville Convertible

    I couldn't figure out why the throttle linkage on my vehicle looks different than some of the others I've seen for the same year. Although the model number stamped on the carb is correct, it finally occurred to me that the base plate (throttle body) is wrong and does not match. As a result, the throttle shaft is wrong and it also explains why the power brake port is too small (1/4"). I broke down and ordered a new (rebuilt) carburetor last night. I think this was the best decision because I also suspected that the accelerator pump wasn't working right. I might have been able to fix power brake port by drilling and tapping for a new fitting. I could also have fixed the accelerator pump, but there is nothing I could do to fix the throttle shaft.

    I am frustrated with these setbacks as this is costing money that I would have preferred to spend in other areas, but the most important part for me is that the motor runs well. On a positive note, I found and fixed another vacuum leak (broken nipple on the vacuum distribution block on firewall) that was likely contributing to the performance problems I've been seeing.

    When I get the new carburetor, I am going to plumb the extra lines for the thermal vacuum switch and replace the kinked fuel line. I've already decided that I will not add the transmission controlled spark (TCS) solenoid because the unit is missing and relatively expensive to buy. Also, it seems that this device can only hurt performance. The only advantage that I see is for emissions and it probably doesn't help that much. Let me know if there is another reason I should add it back in.

    They look similar and being that same year they probably fit but when you fill the compatibility window with 69-70 cadillac the application says itīs not compatible

    here are a few options for seat belts. USA Parts has a few different colors.

    I never use the middle front seat belts so maybe you won't have to buy those. Did you already buy a new carb? I have a completely rebuilt Q-Jet that I replaced with an Edelbrock collecting dust.

    Re: New Owner Red 1970 Cadillac Deville Convertible

    I didn't have much time to work on Rosie this weekend. I started going through the HVAC system. After fixing the vac leak from the distribution block/check valve on the firewall, it seems that it mostly works. I also fixed a ground for the blower relay and now that kicks on. The heater switch on the cylinder head is missing, but it looks like I can connect the wire to ground to allow the heat to kick on (will be missing the delay feature).

    I did already buy a rebuilt carb, but am still waiting for it and the fuel line to come in. Too bad I didn't check with you earlier.

    Thanks all for the links for seat belts. I ordered one belt to see if I like the function, style and color. I'll take pictures if it it looks like it might work. I will probably start to work on some of the interior bits. One of the seat motors may not be working. Also, most of the windows and convertible top will trip the circuit breaker multiple times on the way down/up. I need to pull everything apart and lube them up. I might have to replace the circuit breaker-- do they go bad?[COLOR="Silver"]

    BTW, I might be interested in these, but I am not sure how to send private messages here.

    Re: New Owner Red 1970 Cadillac Deville Convertible

    I removed the rear bench seat last night and I was surprised to find all the rear seat belts there and intact. They are dirty and need cleaning, but at least I won't need to purchase seat belts in the rear. I am still missing the buckles (female end) in the front, but I am hopeful that I have a solution for that as I mentioned previously. The main problem with the rear seat is that the frame is broken in three areas. I am going to find someone to weld them-- can't imagine it is a difficult job.

    I found another funny thing while troubleshooting the convertible top, windows and power seats. I don't know why, but I pulled out the circuit breaker and I discovered that it is rated for 8.25 amps. It is supposed to be 40 amps. When I replace that, it will solve many of my problems. I will still have to clean and lube the power seat mechanisms and window mechanisms, but I think the top is going to work without further issue. Apparently the top mechanism is only pulling a bit more than 8.25 amps as it works (albeit slowly) with the current breaker.

    I also discovered that there is an automatic unlocking mechanism for the front seat backs. I am working on getting that to work. I am missing the manual release lever on the passenger side and its been a nuisance. I can't believe all the little do-dads that this car has. I expect to make a lot of progress over the next few days once the parts start coming in.

    I must be an idiot, but I don't see a private message icon for any user. In the settings, it seems like I should be set up to allow private messaging. My email address is correct (needed for sign-up) and I've enabled the options to allow private messaging.

    I can see the pm button for all of you except for klinebau. Maybe he has not written enough posts yet. The mod of this section could confirm.

    Re: New Owner Red 1970 Cadillac Deville Convertible

    I received the new (rebuilt) carburetor and I attempted to install it, but ran into a few snags.

    1. The new carb has a 1" threaded fitting for the fuel inlet with a 5/8" double flare for the fuel line. This would work fine for a 3/8" fuel line, but apparently I have a 5/16" fuel line and need a 1/2" double flare fitting. Not sure what to do here unless I replace the fuel line.
    2. The new carb has an additional 1/4" vacuum port between the PCV and spark advance port. Anyone know what that port is used for? I can cap it if necessary, but would like to know why it's there. I was under the impression that the thermal vacuum switch was tee'd to the vacuum break line for manifold vacuum.
    3. The new carb doesn't have a hot idle compensator. I could send the carb back, but would like to know if this is really needed.

    Re: New Owner Red 1970 Cadillac Deville Convertible

    Its been a while since I posted and thought I would give an update. The truth is, I haven't really had much time to do much. I did find an adapter and was able to connect the fuel line to the carburetor. There are no leaks and it was immediately apparent upon startup that the car performed much better. After adjusting the idle speed, idle mixture and the timing I went for a short test drive and was amazed... instant throttle response and more engine power. At this point I think I'm getting 100% power out of the engine.

    Of course, this was not without the discovery of new issues. The throttle rod was too short and made the accelerator stick a bit in low throttle angles. The choke was a bit weak and had trouble starting in 50-60 degree weather. Strangely enough, it was easier to start in colder temperatures. Also, the very small valve cover leak has gotten much worse and now the car is not really drivable until I fix that.

    I decided that I can do without the hot idle compensator and probably isn't needed unless extending idling in hot weather with the A/C on full blast. I probably won't ever get to fixing the A/C anyway. The other port on the carburetor was probably for EGR which isn't used on the '7-- I just plugged it. With these rebuilt carbs, who really knows what year the throttle body came from.

    With the 40 amp circuit breaker installed, I am able to raise and lower the top without any pauses. Same with the windows, although they are slow. The seat motors work, but not in all the positions. I am going to have to take a look at the transmissions. My next priority will be to get heat working so that I can install new coolant and heater hoses and effectively purge air bubbles in the heater core.
