I had heard that SC&C were working on a 3-link rear suspension for 1983-1988 GM G Bodies but it seems like its not going to be available in the near future. I've done a lot of research and it doesn't seem like anyone has a kit that would be easily adaptable to these cars at all. At this point I'm going to go ahead and try to figure out how to make my own. I just need a little help from anyone who might be knowledgeable in this area. *If anyone has done this to an earlier A body their help would be greatly appreciated as well because thats probably the easiest place to start (similar frames and suspension)
What I know:
-I want to be able to use the stock rear seat without cutting into the upholstery. Minor trimming of the floor, seat frame or seat foam is ok.*
-I don't want to use the transmission crossmember as my pivot point for the torque arm.
-I want to use adjustable coil-over shocks mainly for packaging to make stock appearing rear exit exhaust possible.
-I want to use rubber bushings at the housing end to minimise NVH
-I don't care if its bolt in or weld in construction
-I want to use a watts-link
-The rear of the car should sit 1.5 - 2 inches lower than stock.
-I fully expect to have to do some major reinforcing of the frame, box in the C-Channel etc
What I don't know:
-How long should the torque arm be?
-How long should the other two arms be?
-Do the lower two arms need to be exactly parallel?
-Important angles?
-Should I use an F-Body 3 link rear end housing or?
-Are any F-Body parts or aftermarket F-body parts worth modifying to use?
-Swaybar? Yes? No? Mount to?
Any help would be greatly appreciated. I'm probably in over my head but I'm willing to learn. I'll document every step of the process and make detailed plans available to anyone else who wants to do this.*

This is the closest I've found to what I'm trying to do. *
Failing this I'm actually toying with independant rear suspension. Something like what team321 offers. It might actually be easier but its got a lot of drawbacks. http://www.team321.com/321HotRodIRS/321HotRodIRShome.html
But probably with the LCA shock mount so I can run stock appearing rear exit exhaust.

thanks in advance for any input.
