On the pass. side of the D60, what is the size of the studs that bolt into the housing holding down the spring plate?

I am pretty sure they are 5/8

depends on what 60 you are running. Chebby is 5/8 and Dodge is 9/16

who sells these. the dealer doesn't have it? anyone have a parts number.

I think the size is (pain in the ass) X (piece of shit)
That help any?
OK really my Dodge is 9/16

I finally found some at a spring shop fro my chevy 60. They are 5/8" x 3 7/8" with 11tpi threading into the diff and the tops at 18 tpi. When I got them home they were way to long for my 44044's. I said fawk it! Now I am using bolts.
