One question I have is how long are your forward trailing arms? Factory length is 14" and my guess is that would have to have been shortened. This may have add problems.

VanSteel can make up a composite spring for you. They actually would have Hyperco make it. But you need to go through a dealer and VanSteel is. VanSteel also make a coil over kit, but then you get into how long are your trailing arms? They would need to be modified and they are damn expensive.

Then there is Dick Guldstrand, that has a nice conversion, that is the way to go in my opinion. However a conversion of that would still be needed.

Added: When I say 14", I mean from the centerline of your half shaft to the mounting point. If this is shorter you would lose shock motion per wheel travel.
