Hi everyone,

Firstly thanks for having me here. There's some great info going around on this site that is always a brilliant help.

I have a BA Wagon. The diff is making hellish noises. Instead of repair I'm looking to replace and upgrade from the M78 (3.23) to a M86 LSD (3.45, Maybe even a 3.9 in time). I know from a turbo manual wagon build on https://www.fordxr6turbo.com/forum/topic/94126-ba-xt-mk2-turbo-wagon-conversion/ (great piece of writing that is!) that I can replace my prop/tail shaft from the one piece to the two piece (ute) by cutting threads in the holes for the centre bearing. And then measure and cut the end piece to shorten and fit. 

Is there any reason why a sedan prop/tail shaft wouldn't fit? Thus not having to cut it shorter. What am I missing? UJ's not flexible enough due to it being a cradle diff?

TIA,
George

 

I believe there's both a length and mounting point issue for the sedan vs wagon tailshafts, but I don't know for sure.
