hilux diff (RN40, later models wider) is same width as AE86 at approx 56 inches wide
have been told hilux will fit 1200 if late camry fwd wheels used (unconfirmed) so ae86 may fit
dazza

bluebird diff is wider than i ke30 diff im pretty sure, and ke30 is supposed to be 3 inches wider than stock

Mitsubishi Sigma/Scorpian is 90 mm wider I think.

The Toyota Corona's also ran a borgy of 114.3x4 I think. Maybe worth checking. . .

Someone already said stanza, right?

I, used a Sigma wagon housing narrowed to 1200 width , changed studs in the axles , fitted original handbrake cables (Almost direct fit) to the sigma ,larger drums ,plus an lsd head . Just looks like it belongs there!!!!.

thanks everyone for your help,ive stumbled across a mystery toyota diff from aldente's collection! he thinks its out of a van or 80s wagon?hes not sure, but all i have to do is weld on my bits where the diff sits on the leaf springs and sort out the handbrake cable and then project fatsun will look the part,cheers!
