BA XT stock diff to turbo LSD

Recommended Posts

Hey guys, looking at putting a complete M86 cradle into my BA XT auto sedan preferably with a 3.73 ratio.


How much work is involved and which models of falcon cradles will bolt in? I've got my eyes on a BF 3.73 at the moment from a 6 speed manual, will this be an easy enough installation?


Also, the one I'm looking at seems to have vented rear rotors, I thought the BA/BF all had solid rear disks. Any ideas on that?


Cheers guys.

22 bolts.


Later model had vented rears.


XT driveshaft won't fit turbo/v8 diff/m86 diff. Rear CV flange is smaller on m78

Thanks mate, appreciate the info. So it's pretty much a bolt in job but I'll have to get a prop shaft from the M86 setup to line up with the new diff?


If I am doing the whole diff in the cradle with the driveshafts, hubs, rotors, calipers etc, I'm assuming it shouldn't matter about the CV flange because it's all M86 stuff.
