Re: 8.5 switch from 2:73 to 3:42 gears

Well I think we should ID the rear to be sure that is what you have before getting all torqued up. The LOW horse BOP FULL SIZE cars did come with 10 bolt 8.5 rears.... so it is very possible... Send a few pictures and we can ID that. NOW if it is a 8.5 10 bolt corporate rear- 2.73 IS a 3 series gear...

Re: 71 Buick 8.5

Fluid will not get your posi back...Probably not even a little. If the clutches are that bad the only thing that MIGHT happen is you will blow your spider gears. Best to pull those clutches and see what is happening then if you need a new set purchase a STEEL clutch set- They are MUCH better for spi...

Re: 8.2 posi

Ok, Well first off your not doing your self any better going from one USED rear to another. NO reliability there.

Re: 10 bolt 8.2 BOP axle housing pins

Re: 10 bolt 8.2 BOP axle housing pins

There are NO plugs... they are holes in the casting that lead to the tube...then the welder needs to hit the tube on the first strike to get a good weld on the tube. I would say THIS IS NOT making your car squirelly shocks spring bushings and frame of the car will make the car feel squirlly and loos...

Re: 10 bolt 8.2 BOP axle housing pins

Ok, I get it now... yes those are holes that are plug welded after the tube is pressed into the cast center. They can leak after time... Not much you can do. we have had success cleaning out the entire differential cavity and getting sealant inside the casting where the tube meets the tubes and load...
