THAT is the source I was going to recommend. Use them all the time very reliable, deep inventory, and fast delivery.h

My local ACE hardware carries a very nice selection of fasteners. Agreed McMaster carr has very quick delivery.

would these fit ?

Nope, those won't work in the tail light housing application. Those cage nuts are designed for relay racks and cabinets where they clip into the smallish (a bit over a quarter inch) square holes.

Available at the dealer I use .

Thanks. Will try local dealer first and then order if needed. Went to Fastenal and other bolt places and all closed because of July 4th - good for them of course but bad for me ;-)

This is where it's nice to have friends close by that seem to keep lots of extra parts in the garage. I have a bag with six of them sitting here, as I try to buy extra of the parts that seem to be a bit unusual or awkward to locate easily and that aren't super pricy. I'd give you a couple as as you seem to be in a hurry, but Calgary isn't exactly close to Texas... ;)

Yea, that would be difficult to do but appreciate the offer!
