Thanks Don, even ARP wouldn't give me a straight answer when I emailed them!!! If there's not a lot in it then I'll certainly put the business your way.
Couple of new questions:
The pins that hold the alternator strap in place - do they simply tap out and if so is there a specific direction they need to be tapped?
Some of my case studs have corrosion on them. This varies from simply not having the plating on them anymore to being completely white or having rust patches. Is it common practice to replace these studs or would I just get away with cleaning them up?
