What's the thread size on EVO case studs

[gryphon]

All the S&S cases use 3/8" thread but someone was telling me that stock they use a 7/16" thread on the headbolt end.

Gryhon,

It's too damn cold to go out to the garage and verify, but I believe they are 3/8" thread on head bolt end.  I remember buying a 3/8" acorn to put latest style of cylinder studs in the case (89 Evo), when I fixed my leak this last summer.  There were 4 Evo cylinder stud versions.  Early 85, late 85, 1988, and then the 1994 was the last version of cylinder studs.

It's 3/8.
