drift car eh? so its already trashed and crashed? only 4 lug option solid rear you have that i know of is the 79-81 mk1 supra. has disc brakes too. its a 7.5in rear instead of the 6.7in, and you can use the same lsd's as the 7.5in trucks, like the truetrac helica lsd i run in my mk2. good luck finding a mk1 in the junkyard though. tons of them ~7-10 years ago. none now.
