hi
i have a xy van that is a factory v8 Windsor it still has its factory fitted 2.92 25 spline 2 pin Borg-Warner
i am contemplating do this conversion my self
turn it to 28 spline axle with either new custom axles or use the 28 spline axles out of a xd 2.77 lsd 4 pin 351 diff i have/ no one wants these as you cant change the ratio and the lsd hemisphere is non useable in 2.92 and up ratios so I'm willing to rob some parts off of it.
things i need to check
1./ if there is enough spline on the factory 28 spline axels to cut them down to fit the earlier xy width.
2./ if the area between the housing end and the face of the axle is the same from a disk brake and drum brake axle
we have a lathe so shortening is easy and turning the bigger spigot on the later axle down to the earlier xy size is simple enough
questions:
things i need to find out before buying parts is do the latter BTR hemispheres from late model 90's cars fit into the earlier xy housings ?????????????
i'll just get a 4 pin LSD 28 spline hemi and 3.08 gears from a vn commodore.
from my under standing the 2.77 axle is a M75 but nothing 2.92 and up M75/8 fits them or vice verser ....the 2.92 and above are either M75 or M78 (definitely M78 from xd onwards)2.92 and up M75 & M78 parts are interchangeable
i may need to machine down the 3.08 pinion to fit the falcon housing
