Im getting ready to upgrade my diff and install 3.73 gears an eaton posi and a performance diff cover. My question is does anybody know what size the ten bolts that hold the diff cover on are. I want to buy new possibbly stronger ones when i have this project done. Thanks for any of the help or info you can give....if buy some chance there is a company that sell these that you know of that would help also.

 

I'd suggest that the diff cover will come with the bolts--my Summit version did anyway.

TA Performance also manufactures them as well. The stud kit is extra apparently:

The stud kit for the T/A Performance cover is actually for the main bearing caps, not the cover itself. The cover comes with the cover bolts at the regular price.

I bought a used cover and it didnt come with new bolts thats one reason why im asking

(Just remembered that I have instructions) For my kit:

Some applications such as the Chevy 10-bolt, 7.5" diff covers will require the use of (2) 5/16-18NC x 1-1/2 hex head bolts (supplied) to mount the parking brake cable brackets to the rear end housing.

I measured the 'normal' bolts and they are as above only 1-1/4. No info on the bearing cap load studs, but as cal30 points out, they can be had in the above link.

BTW, if you'd like install instructions, let me know and I'll type them up.

Hey, I'm bored this moring:
