I have a friend in Seattle Wash. USA who does a kit to install a Toyota Supra diff... Very strong.....

Hell this is nice, just add one Supra LSD and you have a stronger diff ,with 4 pinion gears, than virtually ANYBODY and a full range ring and pinions from 3.73 to 5.37 for CHEEP.

Drilled for US Xratty bolt circle or 2wd Cosworth bolt circles.
