    Not likely you will find much if any direct support for your particular year and model. If you do a search at rockauto.com they list variable rate (progressive) Husky and Moog for your application but you will need to cross reference those model numbers at the actual manufacturers site to be sure they will fit your mounts and to determine the loading range. You can get any spring length and constant rate you wish at a1racing.com but those are for coil over applications and will probably not work with your mounts. Eibach makes the broadest range of lowering kits but again not likely for your car.

        Unfortunately most of the vehicles that came with our beloved 60 degree motor don't have a large aftermarket. There aren't a ton of true 'bolt-ons' that simply go together with the most basic of hand tools. Many require special tools, modifications like grinding or welding or a combination of all three.

        The good news is that in an effort to keep costs down, GM used many parts across several platforms and ranging many years. Being a W body guy myself, I have several platforms and later generations of W bodies to take parts from and easily fit to my Gen 1.

        This is probably one of the most important things to learn when modifying a GM. As they improved parts many of them can be directly bolted up to the old application, and with many platforms sharing parts it means an upgrade for one car can be retrofitted to other cars. Sometimes taking a glance at other forums can yield valuable insight to projects for your own GM project car.

        One valuable tool to use is parts cross-referencing. For instance, when I am looking for upgrades or just looking to widen my search for parts when I hit the junk yard, I check out Rock Auto. You can find a part and then click on the part number to bring up a list of vehicles and years that share the same part.



        According to that page (I checked it out after looking on Rock Auto) it says the A body and a few other cars were based off of the X platform. If you look up the A body, it shares many parts with the W body and U platform vans. That's a wide variety of cars to take parts from.

        It might take some hunting around on forums or a few trips to a junk yard but there is a reasonable chance that if you find a car with the same drum brakes as yours that had an option for disks, that they probably bolt up to your car with little to no modification. It probably involves removing the drum brake back plate and adding on a caliper bracket. There might be some sort of emergency brake cable rerouting and I didn't search in depth to see exactly what is out there, but it is definitely worth the effort to check it out.



        That thread has a long winded post from me that has some good information for any FWD GM (and perhaps other vehicles as well) for making custom adjustable coil overs for your car. If you check out the link there to the W body suspension thread, it shows what you need to remove from the strut housing to make the threaded sleeve fit. Many other vehicles have the same or an extremely similar strut setup. Going by the pics on rock auto it looks very similar to the Gen 2 W body strut. Double check the diameter but I'm willing to bet it is the same. If you check out another of the links from the other thread, A-1 racing has several diameter sleeves. Find the one that is slightly larger than the diameter of your strut and you can put together a nice adjustable suspension for hardly any more money than it would cost to replace it all with stock pieces. Rock auto even has KYB GR-2 shocks for the front of your car. Hunt around and you can probably find something for the rear as well.

        Hunting down what fits is really the hard part. If you look for kits custom tailored to your vehicle, expect a custom tailored price tag to go with it. Most of this stuff is fairly simple and rather affordable. Search the forums, mock parts up on cars at the junk yard, and post up questions if you need any help!
