The g body suspension configuration doesn't lend itself to coilovers that well. Coilovers really need longer springs that what is easily fit in a g body.
What you gain when you do coilovers is adjustable ride height from the adjusters. You can buy some dirt track spring adjusters off speedway for $25 each and weld them in, a good set of springs and adjustable shocks for less than a good set of coilovers and it will fit and work better.
Coilovers are really for McPherson strut or other setups and somehow have bled into the parallel link market found on older stuff.
