right i will keep this brief i am running a 7 inch 3.62 lsd diff at the mo and i have a 3.38 7.5 diff that is not lsd i want to know if it is possible to put the crown wheel and pinion into this casing and keep the lsd in there as well. has anyone experience of this mod and how hard is it for a man in his garage with no special tools or knowledge of stripping diffs down any help would be great

working on diffs and getting the gear mesh correct is quite tricky and best left to someone with the right tools

been thinking of something similar myself, decided to find a gearbox/axle specialist instead. far too much to get wrong. very wrong

I didn't think you could swap the CW&P between a 7" and 7.5" (feel free to correct me)

but you could always get a 7.5" LSD from a cossie and swap its internals (and sell the 7" LSD)

a granada 24v cossie (pre traction control) will have a 3.64 7.5" LSD with 100mm bolt-on CV joints (same size as 7" bolt-on's) - not sure about the driveshaft lengths though :?
sierra 2wd cossie's have 108mm ones (so you'd need to do something about that )
