This is good info, let me add some. The 7.5" LSD is I believe only available in Gen 2, which is 82-86 Supras. Look at www.car-parts.com under Carrier. The F293 axle code (on the VIN plate) means 4.10 gears.

<strong>There certainly is a 7.5" Supra LSD that will fit in the front diff, and they can usually be had for $50 or less at the local P&P.

These were the optional LSD's used in the Gen. I and Gen II Supras. You have to remove a little (1/4" or so?) of excess material on the ends of the front truck stub axles to get them to work with the Supra diffs, but otherwise i believe they are plug and play.

Easiest way to identify these diffs is from the axle code: you want Fxx3, where F = 7.5" and the final 3 = two pinion LSD.

Another identifier: the LSD's had a finned rear cover with a sticker that reads "LSD oil only".
