I am wondering how to check exactly what differential is in my 1989 Toyota pickup 2wd. also I want to find out the cheapest and easiest way to lock up the rear end. I am trying to make a truck that will go sideways on pavement for drifting. any help would be great. thanks!!!

 

This is not the correct place to post this, but Ill answer your question.

Look here for diff information.

Cheapest options to lock the rear end in this order: Weld it, spool, locker.

Use the search bar if you dont know what that means.
