Does anyone make the metal post that is mounted to the body which several ground wires attach?
Thanks Brian

It would be very easy to make; just a washer, and 6 or 8mm stud welded together, welded flush to body location.

This ground post looks like a star which I think four or five ground wires stab onto and is welded to the body.
Thanks Brian

Thinking out loud... Can't remember one like that. 5 posts on one ground. What's the location?

Have you looked at the RD site under hardware ?

They are up on the back of the head light assembly.

Pem Stud

Without seeing it in person, I'd say it was a pressed in stud that was spot welded to prevent it from loosening.

Your best bet would be to cut it out and weld in another sheet metal stud like shown in the link or weld in a bolt or stud. Depends on how good you or your welder is.

Yes it is spot welded to the body.
