I have a 1990 Pick up with a 4 speed trans. what year 4 runner or which truck can i pull a 438 or 456 rear end from and install without any mods. Please help trying to work on my truck just bought it and i'm pretty excited about it.
4spd?should be a 8 inch diff.late 70s-94 pre taco and 84-99 non e lock 4runners.most auto trans were 4.30:1.not sure which ones came with 4.56:1 although I've bought em out of other trucks.My 87 1 ton came with a 4.30:1. Good luck!
I've run 4.10s in all my 2wd's with good results. Not sure off hand where these rears can be found, but this site helped me a ton when going to junkyards: http://www.brian894x4.com/Gearratiosanddiffs.html
