If you use Sierra as donor can you use Sierra rear axle crossmember,lower suspension arms springs and shockers?
Wanderinstar.
It would be a tad heavy not too mention look crap
the springs are far too powerful for such a light car, and the pick up points arent ideal for either the springs or shockers.
i have used the rear subframe and trailing arms, with brackets welded on for gts shocks. Whilst it has saved me some time, i would strongly advise
others not to bother - it weighs a crapload, and is quite wide (hard to cover by bodywork).
much better (more satisfying) to make a 'proper' backend.

Buy a GTS dedion kit and be done with it.
