Hello - i've got a chance to buy an 80 toy 4x4 with a 20r engine thats bad, i've got a small toyota junkyard of 8 trucks from 85-93 toyota, so i've got several good 22r engines from 85-93 , will an 86 22r bolt up to a 1980 20r transmission ?? thanks in advance !! I dont have much experience with the 84 & older toyota trucks and what will interchange !
