Okay, I have a 86' 22r Xcab Long bed 1/2 Ton with a F302 Rear end in it. According to forum browsing that means I should have a 7.5" 2 pinion, Open Rear, with 3.73 gears. I am working to get the truck to be capable of the occasional drift event (stupid, I know), so ideally I need something that is not an open diff. The only thing I was able to find as far as a Limited Slip that I could drop in was this >Truetrac Limited Slip< from LCE. Supposedly I can also grab the diff out of an older Celica/Supra as some of them had 7.5" rears with LSDs but I have read conflicting information as to what would bolt in and what would need fabrication. Theoretically I also swap my rear to the 1 ton truck axle which is an 8" rear and has a couple more LSD options. Has anybody here tried any of these or am I missing another obvious solution? Also, I'm thinking of swapping my W56 to a W58 coming out of an 82' Celica. I saw that some of the members on this forum had it done this swap and really appreciated the taller gearing. Thoughts?
