what all do i have to do to run a 4th gen rear end in a 82 third gen i heard its not hard any info will help

 

It's a direct bolt in except it's about 2" wider on each side so your stock third gen wheels will stick out.

 

not to hijack but most guys seems they run a 15x8 with 4.5 bs on a stock rear so on a 4th gen would you just add 2in of bs to the wheels so it would be 6.5?

 

Its a direct bolt in, other than E-Brake cables hookup a little different, they are a little bit shorter on the 4th gen rear. I got mine to work so its not really a big deal. And... if your 3rd gen has drum brakes and the 4th gen has discs, then you will have to get a different porportioning valve, one for 4 wheel discs. And I believe the 4th gen is 2in. wider all together, so 1in. each side. Get some wheels with a 5.5in. backspacing.

I think that is it. Good luck.

 

Ah but I said, "The stock wheels will stick out"

You can use fourth gen rims or an aftermarket rim with the proper backspacing to correct for the wider housing.

 

im trying to make shur i get the right bs for my aftermarket wheels before i go drop the 600bucks and they dont sit right, and i heard it was about 2in per side so 4in widermm better go make shur
