Thes grey MSI studs are not as long as I’d like, but they might work in this spacer. The gold stud is an ARP, but they don’t make one in the knurled width I need.
Looking at the dimensions, should I try to open the hole a bit?
From MSI: This stud is designed to work with a 14mm (.551 -.557) diameter hole in the hub.
Then it would be find the drill bit to work.
