I changed the fluid in my rear diff (RP 75w-90) and could not stand the site of the corrosion on the rear differential cover bolts. I ordered a set from Summit Racing to replace them. In case anyone wants some, here is the info:
Summit Part Number: ARP-613-0750
ARP Part Number: 613-0750
These are 12-Point Head, Stainless 300, Polished, 3/8 in.-16 RH Thread, .750 in. UHL. They are rated for 170,000 PSI (better than grade 8). You will need two packs since they come 5 in each.
