AAAAAH POOP!....I had my passenger side out & apart till this mornin an I put it together and riveted it, here is the best measurements i could get.
the stud is 5/16" standard thread.
From the edge of the frame to the shoulder of the flat is .205
Approx. .035 ground off each side of the stud..it measures .220 thick with the flats
Overall length of the stud is 1.905,I would guess that 1/16" is in the frame before welding making the total length of the stud 2"
