Hey all

Hi all,
I am new here and just recently picked up my old k30 4 door longbed 4x4 I have a bunch of questions, but the one I really need quick answer to and can't seem to find:

-on the rear end (I have full floating axles) not the lugs obviously, but there is another set of bolts that holds fluid in the rear end. Can anyone give me the dimensions on these bolts? I need to pick up two. Also, what do yall fill the rear end with in your trucks?

Anything would help, thanks.
