Front suspention question
 

I am building a Ls powered 66 mustang tube frame all wheel drive with c7 front spindles and a arms. Hoping some one with c7 can give me a couple of specs. How wide is front mono leaf bumper to bumper loaded. Also how much ark from bottom of a arms where bumper is to center of leaf. Doesn't half to be perfect just close want to use mono leaf don't know if it's to wide or not. Am flaring fenders,front drive train wider than mustang but not sure if wide enuf for leaf. New to post will post picks soon but don't want to let cat out of bag too early want to take sema by storm in a year or two. Any help would be greatly app. Thanks, Wolfman
