as title - I have the possibility of an lsd out of a 4x4 cossy which is a 7"

can the lsd be removed and fitted to my 7 1/2" crown wheel/pinion ?

I was actually miss sold a 7 1/2" diff which was supposed to be an lsd but when I removed the rear casing found it is normal free diff with planet gears

Hi Mick

Acording to Steve Heaths S Bible the best route is to get the rear half of the 7" propshaft and fit it to the front U/J (assuming same sizes apparently the sierra had all sorts of combinations) on your prop shaft.

BTW I've seen references to 7" and 7 1/2" diffs a few times now but arnt sure where you take the measurement from had assumed the flange at the front buts now I have stripped mine its obviously not that
