1971 and later is in fact 1/4-20 with 7/16" hex ----- trust me.

Ron,


Sounds like the ones at R/T Specialties are for 1970 and earlier. They don't specify a year in their link.


Yep those are earlier but these look like the ones Bill Alphin posted and few other's. Problem though you need 4 total.
