I have a 1990 454ss it has a 14 bolt rearend and was told 373 gears but it does not have positraction it is 5 lug. I would like it to have positraction. My thinking i would take the internals out of another rearend and put it in mine to get 373 gears with positraction. While looking at different rear ends I have come across a 88 3/4 ton truck rearend. It has 373 and posi and is a 14 bolt rearend but it has 8 lug axles. Would i be able to take the gears out of this rearend and put it in mine? also would like to know what other rear ends would be compatible does it have to be 2wd?
