Can someone with an 86-95 measure the width from back of drum to back of drum on other side for me please?

Also do these years models that had the thicker rear end on the v6/ turbo Toyota/ pickup/ 4runner have the same width as the 4 cyl rear end?

V6 & Turbo diffs have 4 spiders gears in the rear third
4 Cyl diffs have 2 spider gears.

I don't actually get what you mean thicker rear end..been messing with these POS's for 34 years

Below pulled from Pirate FAQ

Thank you, ok so the difference is 2 pinion vs 4 pinion on the 4cyl to 6 cyl rear ends.

I know the 86-95 is 58 inches wide at the flangeto flange aka wheel mounting surface, but I need the measurement from the back plate to back plate, I believe it should be about 50 inches.

2 and 4 spider gears..each diff only has one pinion gear.
