Hate to ask what may be a dumb question

The factory nuts are interference type lock nuts. Here it is almost 50 years later and it is very easy to break the studs off because of the death grip the nuts have on them. Mopar engineers were VERY anal about things like that and sometimes tended to over-do things. Really? These nuts are going to vibrate off?

Last time I did this I had the header panel on a bench with the grilles still in them. I actually used a Dremel tool with a small cut-off wheel to cut through the nuts enough that they practically fell off. I was able to save every stud doing it that way.

Then really going to extremes, I replaced the factory studs with stainless steel ones I made from machine screws with the heads cut off. Then I used brass nuts. Lot of work but they'll come off anytime I want them to.
