Found these at the local hardware store in the section where they keep all the little specialty items (nuts, bolts, fasteners, etc). The box had a part number of 58659 and was probably from Hilmans. It says "Push fast variable depth" 7/16 flange X 5/8 stem. The head is probably 7/16 and it is about a milimeter in diameter narrower. The length is 5/8. It also says "Ford/GM"

The picture isn't focused very well (automatic camera wants to argue over what I am taking a picture of). The rivet on the left is the new one, the one on the right is the original.

Thanks. That gives me an idea of what to look for. I do have a batch of black POM rivets that I will try when I put the big LEDs in my 73.

I couldn't find anything like original so I used Stainless Steel finish screws that sit in a SS cup. Looks nice on the charcol/grey/black trim. The one IdahoKid shows would work and removable without losing the little pin.

Found a reference to a Subaru part that is supposed to be the same. Can't find much on the web so you will have to check with Subaru if it works:

Number : 665533000

Name : RIVET, LUGG SLF

Brand : Subaru

Price : 0.04 USD

Weight : 0.00 lbs.

I measured the plastic rivets on a 71 240z rear finisher panel: 5mm or 3/16" 6 required.

I driiled the hole out a very small amount and used an interior rivet.

That's what I did too. Not a problem unless you need to keep it original for a concours show event.
