Can anyone tell me where to get the tail light housing rivets for a 73?

I've not yet been able to install my newly rechromed rear bumper, because I don't have the clips to install the tail light housings in the bumper. I've tried getting them off of 3 different Chargers but it's almost like you have to replace them because they will not come out together. The 73 Mopar parts catalog calls it a rivet. I think I checked the locator and a couple places have them for like $6 a piece for a little plastic clip. I can't see paying that much times like 6 or 8 however many holds it in. I tried getting one off of a Charger today to try and match up at a parts store, but I only got the head. I tried RT Specialties and he said he could get them and would send them as part of my previous order, but it's been over a month now and I haven't heard anything from them. Does anyone else make them?  I was going to take a picture but there isn't even enough left to take a picture of.

I simply used a fastener on housing locations and screw through bumper hole, since I remove periodically for good cleaning an touchs up!

used plastic fasteners, similar to the license plates one but tiny ones to fit on holes

not exactly sure what part you're speaking of, but if you send me a picture of where they go i'll check my old housings and see if anything is usable.....
