One thing that's got me stumped is im not 100% on the diff it has. Some forums say anything NA has the m80 but I've also read anything with a zf6 has an m86 2.73. Ive checked all the labels the only info they give me is 2.73 ratio which could either be m80 or m86. When I had the cradle out I happened to have a m86 housing and from my dodgy measurements and visual inspection they appeared the same, but does the m80 look significantly different in anyway? Sorry for the ramble I just want to be 100% (im about 80% sure its m86) before dumping $1500, pulling the cradle out and finding I don't have the m86. Cheers!

Does the m80 and m86 share axles/splines? Link to comment Share on other sites More sharing options...
