Found my shifter bushings broken/missing a few weeks ago and having a hard time finding a replacement. Searched forums but could not find the bushing i'm needing. Luke say's I will need to replace the whole shift lever, that they do not sell just the bushings. Has anyone found a replacement for these? Mine were completely gone. Does anyone know what the dimensions are? ID / OD / length / shoulder thickness? I may be able to make something up with some help of a machinist at work.
there the white bushings in this picture.
I have resigned them to fit tighter and have them made out of Delrin. PM me. I can ship them this am if you let me know soon enough. Those are actually a set of mine in that photo above. I send the two Delrin bushings, the stainless steel pivot tube (shown between them in that pic) and a new set of Viton o-rings. You can e-mail me and I'll probably get it before a PM. br_1868 (at) hotmail (dot) com.
Or.....you can send me your shifter and I'll modify it into a short shifter and replace the bushings and send it back within two days.
Thanks Brian for the reply. There is no rush as I am currently working in China and won't be back home until the end of the month or so. I tried to read thru most of the shifter threads last week and thought the bushings I needed were the UUC bushings that you no longer carried. I some how got twisted up some where in the thread. I’ve got a temporary fix in there now with Teflon wrap and washers on the side to get it back together before I went back to china. Hope you didn’t mind me using your picture as it gave the best illustration of the bushing. Anyway I’ll pm you my info.
Mcmaster has the bushings you need for next to nothing. I cant remember the specific dimensions though, but I do have a shifter lying around, I could do a few quick measurements. Gimme a couple minutes.

Ok, the McMaster part numbers for bronze bushings that fit in the shifter:
Either 1 of each of these:
5448T12 ---- $4.53
5448T13 ---- $6.03
OR 2 of these:
5448T12 ---- $4.53
The difference between the 2 is one is 12mm long, the other is 20mm long. If you put the 12mm wide and 20mm wide bushings in there, they are 32 mm and exactly the same width as the shaft insert. If you want to keep it simple, you can order 2 of the 12mm ones and have a little gap between them inside the bottom of the shifter. I'd order 1 of each.
The bolt that I used to tighten everything up down there was an AN5-20 aircraft bolt. The OD of the bolt is 5/16, which is nearly an interference fit with the inside of the shaft and the shifter linkage holes (what we want in this case). The shoulder is 1 9/16" long, which puts the shoulder all the way through both ends of the linkage, keeping the slop out. You might need to add a couple washers on it so you can tighten the nut down if the shoulder is too long, so just have some 5/16" washers handy. You can get an AN5-20 bolt at aircraft spruce for $0.42, part number AN5-20A. Then just get a 5/16-24 nut of your choice. I'd use McMaster part number 95307A600, but anything will do really.

Oh, one thing left to mention: the steel insert on the bottom of the shifter is 1.28" long, the bottom of the shifter is 1.1" wide. That means that the thickness of the flange on the bushing needs to be about 2.2 mm. The thickness of the flanges as listed by mcmaster is 3mm. Close enough, but you'll probably need to sand the flange side down a little bit prior to installation. The way to tell is if you install all the bushings and steel insert doesn't stick out past the bronze just a little bit, you'll need to file or sand the bushing down until it does. Otherwise, when you tighten your bolt down, it will clamp down on the bronze and your shifter will be locked up. The steel insert needs to stick out just a hair for free movement.
I just did the upgrade with killernoodle's McMaster bushings. Ground down the flanges so about a half a millimeter of the factory sleeve sticks out both ends. Shifter went from 1-3/4" of left-right slop to less than 1/2". Nice-n-tight! Thanks for the part number references killer!
P.S. I didn't like the factory fully threaded bolt so I switch to a 8mm, that was smooth shaft for the length of the sleeve, then threaded.
Thanks. I was looking at McMaster Carr also for bushings but I was looking for replacement plastic I wasn’t sure if the brass bushing where going to be too stiff or binding on the linkage? Have you installed a set of these? Does it send the vibration up the shift lever? Are they press fit into the shift lever?
I was able to reuse my plastic bushings when I installed my billet aluminum shifter (not sure of the manufacturer). I don't see the brass adding to the vibration much if you still have a rubber isolated stock shifter. My all aluminum shifter and knob definitely transfer the noise and vibrations from the transmission though.
The bronze bushings should just slide in like the plastic ones. I don't see them being a press fit.
I have PISNUOFF's short throw shifter set up and if I was doing it all over again, I would buy the same set up or what ever components he had to offer. His products are excellent and he is a stand up guy. And yes, PISUNOFF's short throw shifter is the best modification, for the money, that really improves the driving experience. Get the whole set up and be done. Hope this helps.
I did my own short throw shifter, but picked up the Delrin bushings from PISNUOFF. Works great.
I also have some parts left over from a used, take-off shifter sitting at home. (I used the lever as my donor for modifying, but have the bushings still.) I got the shifter off Ebay; although it was used, it looked virtually brand new. If anyone wants the bushings, just shoot me a PM.
I had the same issue, but I knew I had a UUC short shifter....Lindsay Cadillac said they couldn't part it out either and I'd have to pay for a whole new one. So I just called UUC directly and they sold them to me thankfully.
