Where is the thread with the ARP main bearing stud part numbers?

Anyone purchased them, do the studs fit the caps like the stock bolts do or are they a generic straight stud?

The stock bolt has the bosses that locate the caps not just a straight bolt..

Since when are the stock main bolts tty? I know the stock head bolts are. But I was under the impression that the stock main bolts were a standard reusable bolt.

My main bearing studs were made for Bill by ARP which will make them for you. When I was stupidly thinking of rebuilding the truck's motor myself, I called them and couldn't get the info. I didn't have the original bolt to even give them the specs but, that may be an option for you to consider. I imagine they would try to source the order from existing stock first. Cheaper for you and them. Can't hurt to give them a call and tell them you need an 'X' length stud at "Y" thread pitch.

Not sure what is in the "kit" offered, but, the ARP single stud part numbers are around here and there. One example:

ARP doesn't offer single studs on their website, just kits, and the main stud is not a kit "ARP" offers. Others do...

I am asking because I don't know and couldn't figure it out: Not sure how the main bolts locate anything because they feel sloppy to me when I just put a main bolt in a main cap hole on the 6.2 here. Perhaps this is why the DSG main stud girdle only has 6 studs total?

Sloppy quick and dirty measurement indicates the (DSG Kit) ARP Studs are thinner than the main bolt upper shoulder, but thicker than the OEM bolt the rest of the ARP length. The section below the OEM main bolt head may have a taper.
