I need to know what the specs are for the $1200 Mopar Head stud kit. Part Number P5007912

Most places are running out of stock so they are getting hard to find.

That said, I talked to ARP a few months back and they said they had nothing in their listings for the W9-RP. BUT if I had the specs they could get something together for me.

I know they are 1/2" dia. in the block and 7/16" dia. through the head. There are 3 different lengths. 2 sets are 10 pieces and 1 set is 16 pieces. 12-point nuts.

If I can get the lengths I think they could figure out the rest and put together an affordable set.

If someone knows all the details that would be awesome.

I used to have a set but "Storage Thieves" wanted them I guess!
