visual difference between 7.5" / 8" housing?

[AE25]

so im looking out for an lsd head. but due to there being two sizes fitted to the jzx, is there any tell tale sign that it's one size or another just by looking at picatures? 7.5" and 8" have the 6bolt albeit difference size bolts.. cant exactly differentiate them from a pic.
any tips appreciated
cheers

There are visual differences between the F & G series housings for the X chassis, best bet is google or jump on yahoo Japan and trawl through auctions to gather pics of the housings to compare.

I'd say 99% of the G series LSDs will be from turbo vehicles, so will be 8" anyway.

Its a pretty tricky one to tell, mainly tell from the axles, and maybe driveshaft uni?
