Tired of junk thermostats. Going with NOS. Do I need to drill a hole in in?

I recently bought a box of 10 (not in factory Mopar) boxes aftermarket NOS all US made t- stats from eBay. It came from Canada and "customs* seemingly had them forever. I have ordered parts from Canada before including from members of this site and before this one transaction I usually get stuff from Canada faster than I get stuff that originated within 3 hours of me .. the 79 and newer V8s take the same stat as every/6 I have ever had my hands on. So far I have used 1 and it's working fine. Not all were stant (at least as packaged, they might all be for all I know) some were packaged private label (I think a couple say "Texaco" on them as if sold by a gas station service center, etc) not looking at the box.... But when I did all individual ones said "made in USA" on them and all were definitely older stock. A thermostat isn't something that i'd be afraid of an old one from the shelf.

It helps that I put an aftermarket temp gauge in the vehicle that thermostat is in along with the original one... I have them both connected and working. I much prefer "mechanical" gauges when possible vs "electrical".

I've had vehicles on which for years and never had to change a thermostat even once, (or maybe ONLY once) and I've had others that I've had to replace them twice a year every year I owned them....
