Building a '53 Willys CJ3a rock crawler, but the length of a CJ7 as cheap as I can, but functional. here's the question:

I have a pair of my old full size stock Chevy Blazer springs, which have that "reverse arch", they are only 2 leaf, but what the hell, it held the Blazer up fine. I just recently aquired a complete set of stock wrangler springs 4 leaf fronts and 5 leaf rears. The Chevy springs are obviousley a little wider and longer and the wrangler look flatter. Can I use the Chevy's up front and maybe combine the two sets of wranglers into one pair and use them for the rear? Or forget the Chevy ones and stick with the wranglers, or shine the wranglers and look for another pair of Chevy springs??
