the rear window in my 68 convertible stopped. i took off the door panel and it looks like a bolt that connects the regulator to the gear has come out. i found the bolt but it is not threaded.
any idea how this connects to the regulator? is it pressed in?
how do i replace it?

I believe its a rivet and its swaged in place. You might get by replacing it with a Gr 8 1/4 inch bolt and a locknut.
