it's been a while sense i've been on here. i sold my 406 car & the wife's ss got stolen.

i bought another 85 ss & i'm building a nice 383 sbc & 400 turbo & i need a rear end. i'm thinking of going with an explorer rear & doing the two short side axles, but then there is the fox body that will #### near bolt right in. i'm pretty sure the hole in the mount for the lower control arms are about an inch forward compared to the factory gm location, & the uppers will need to be adjustable with the box's put in the frame to get the instant center corrected. but what about wheels? i would have the axles drilled for gm bolt pattern, but what kind of back spacing would be needed to tuck a 275/60-15? just how much trouble is this going to be? is it as easy as everyone says? what about the cost factor? keep in mind i'm a welder/fabricator. so if i was to use the explorer rear end i would have to fab a truss system for the upper control arm mounts & put the lower brackets on. i would end up with about $300 bucks in it with a posi, 3.73 gears & 31 spline axles. the fox body rear end install kit costs more than that, but is it worth it?
