I purchased front (suncore 404G-12-F) and rear (unity air ditcher) conversion kits. The front isn't the complete assemblies, only the struts. A couple questions: 1) is there a kit I can buy with mounting hardware ie: springs and mounts and/or does anybody know exactly which parts I will need to complete the conversion? 2) my mechanic expects issues if I only have the rear conversion done while figuring out the front parts to get. Is this a correct assumption, or will it be ok to only do the rear first and do the front later? Sorry if my question isn't clear, busy day and I'm in a hurry, no luck with my search queries. If there's anything I'm overlooking any and all help would be great , thanks.

For the front, you'd be much better off buying Monroe struts.

For the rear, eliminating the ELC (Electronic Level Control) system is a bad idea. The stock springs are too soft to keep the car at proper ride height. Some conversion kits use helper springs. These cause a harsh ride, the ride height can be too high with no rear passengers, the rear can sag under heavier loads, and they can be noisy.

Your best bet is Monroe ELC compatible shocks. If your compressor is bad, a new one is around $215, or you can use a ~$15 manual fill kit.

A $1.19 pack of resistors can be used to keep the computers happy. The installation is very simple, and has been covered here many times.

Seriously, if you can return the Suncores, do so.

===================================
STOP -
return everything you already bought -
start over -

I will give you a list of parts that will SAVE YOU MONEY -
AND give you a MUCH better ride -
------------------

for the front struts -
I recommend Monroe kit -
it includes EVERYTHING except a new spring -

90011-1 - RIGHT - $127.23 - including shipping -
http://www.partsgeek.com/dp6cxvc-cadillac-deville-suspension-conversion-kit.html?fp=pp

90011-2 - LEFT - $127.23 - including shipping -
http://www.partsgeek.com/w7pnfvr-cadillac-deville-suspension-conversion-kit.html?fp=pp

---------------------

if the strut bearings and mounts are still good - just replace the strut -
Monroe 30142 - $26.82 - each -
$61.71 - for the PAIR - including shipping -
http://www.partsgeek.com/pr1b8kh-cadillac-deville-strut-assembly.html?fp=pp

NOTE -
the suncore strut "kit" you listed isn't a "kit" at all -
it is just a pair of struts -

--------------------------------

for the rear shocks -
getting the coil-over type shocks is a BIG MISTAKE -

they ride like a 1-ton truck -
they are often quite noisy -
the rear will NEVER be at the correct ride-height -

without a load in the back seat and/or trunk -
the rear WILL sit too high -

with a load in the back seat and/or trunk -
the rear WILL sit too low -

if the ELC - Electronic Level Control no longer works properly -
you can still enjoy the true Cadillac ride -
and maintain correct ride-height - manually -
just like inflating or deflating a tire -

for rear shocks - I recommend the
MONROE 40046 - $99.64 each - with free shipping -
http://www.amazon.com/gp/product/B0047D9TS0/?ie=UTF8&me=ATVPDKIKX0DER

and the MONROE AK29 manual fill kit - $12 -

-----------------------------

to "fool" the suspension electronics -
You need 4) 4.7K Ohm 1/2W resistors
RadioShack #271-1124 -
about $1.50 for a pack of 5 -

Thank you, very eye opening. It looks like I should have researched that purchase a little better. Is there a collection of links to become better informed on these ELC systems?
