Hello! i'm new here and I have a 2000 SR5 2WD which I'd like to give more Prerunner/Offroad capabilities. My door sticker says: A01A which means a 7.5" 2pin open diff. I was looking at different lunchbox style lockers but they're all either for the 8" that comes in the 4x4 rear or the 7.5" that comes in the 4x4 front. Are there any specific rear 7.5" lockers (A), could I use a 4x4 front locker in my rear (B), or should i swap the whole axle for an 8" and get the Aussie Locker(C) Thanks in advance.
