ARP rear cover bolts
I plan on installing a TruTrac into my truck soon and I'd like to get some nice ARP rear cover bolts to top it all off. I've done this to my '78 Z28 and I want to do the same on my truck. I've searched this website and some people think I need ARP # 437-3001. However, other people are saying ARP # 771-1005 are the correct bolts. I don't know why there is confusion because the bolt thread and lengths are different between the two part numbers. Please tell me which bolt part number is correct. BTW, I plan on using my stock rear cover. Any info would be appreciated!!

The bolts I have are Fastenal Bolts(M8 X 1.25 X 35) and they are black. I got mine due to the cover I bought. My bolts needed to be longer (as well as stronger). My rear cover bolts are metric. Stock is M8 X 1.25 X 20.
The 771-1005 ARP's are M8 X 1.25 X 40. Which is perfect for me or anyone else putting the large cover on. They are longer. (I believe they are black, but don't quote me there)
The 437-3001 ARP's is ARP's replacement bolt for the stock ones in the Chevy 10 bolt rears. I believe they are stainless steel. These are gonna be the ones you want. Just verify before ordering they are indeed metric.
