Default Lost ARP nut - LS2 head stud - small

I am hoping someone can tell me the thread pattern for the small stud of an LS2 234-4317 head stud kit? I want to get a replacement nut.

I would do it myself but we had to evac my county. I am near a Sunmit Racing in Ga and on our way back homeowners am planning on stopping in there. Thanks

The instructions for that kit say to use the following thread chasers in the block:

912-0011 (M11 X 2.0) and 912-0001 (M8 X 1.25)

If the nuts have the same thread as the end of the stud that goes in the block, then that is your answer. Hopefully this helps somehow/eventually.

In case anyone runs into this, the small stud is 5/16", nut P/N is 300-8301. Summit Racing has them for $1.50
