C body 8 3/4 swap

-- I have exactly that set-up (cut housing and axles) in My Valiant. I don't know the dimensions - I bought it already converted, and I can't measure it, because I'm in Florida, and the Valiant is in Pa. -- Perhaps my dimensions would be different anyway - My car is a 69. -- I've had "C" Body axles cut, re-splined an put into A-Body housings on other A Bodies in the past. Those axles have more meat, and have worked well for me, in 11 second cars. -- Good luck.
iam in the same boat,iam rebuilding a 65 dart,already have my rims ,centerlines 9" hoping to pit 275:s or 295"s,,what kind of job is it to have the x shorten would you think,thanks
