Sorry, meant to get back with you on this. I guess the question would be; Are the factory mounts still there for the coil spring suspension? There should be a pair of spring pockets, two mounting points for the trailing arms, and a Panhard rod mount. If they're all still present, swapping the stock style suspension back in should be realtively easy. If not, you may have to track down some parts. I beleive the trialing arms are avaialbe new, as they're more or less the same as what you'll find under a Nascar stock car.
