8.8 swap

you really need to jig up the rearend to weld it back together. it is only partially about warpage from welding. the rest is getting it aligned up to start with. i have done hundreds of rears and from experience that they are rarely truly straight to start. fords tend to have a little offset in the ends. extremely easy to be off angle,center some and the only way to be sure later is to put it on a good 4 wheel alighnment machine that can ck caster,toe in and that will still not show how well aligned in the vert,horz planes. my advice find someone with a jig and get it done right. I have never seen a home done one be completely right. my 2 cents.paul
