Anybody know it. It's the one in the frame. Looks like 5/8 or 3/4. Mine is wallowed out and I'll need to have it repaired.

More fun.

herb,
on my 67 gto it measures 5/8".
funny you should ask. i just measured it last night.

Thanks!!!!!!Now all I have to do is find a nice thick 5/8 in. washer and weld it on each side.

:thumbsup:

depending how bad it is wallowed out, i would just weld the washer on the bottom.
then it would look real clean when the rubber grommet is put on.

Interesting response and a lesson in communications. I meant on the left and right side of the frame, I.E. BOTH sides.:D Good tip though, hadn't considered welding it on the bottom of the mount.:thumbsup:
