Headlight Adjustment Nut

[claybreaker 144]

I recently dismantled a pair of headlight buckets to restore and broke two of the nuts that the headlight adjustment screws go into. I have several extra headlight buckets that I could harvest the nut from but looking at the broken parts from the one I dismantled they look like single use only parts.
Anyone have an experience with these (removing and reuse of the nut) they could share?
The only search results I found for this part was a post from Jim Wulf in 2013 where it looks like he acquired some of these and was looking for help identifying them.
Replacements are $15 each (crazy) at Tbird suppliers and the photos look to be a standard nylon replacement insert which is not the construction of the original. I did find a Mustang supplier (Auto Krafters) that has replacements for $2 each and they say they will fit 61-63 Tbirds, That will be the direction I will take if I can't reuse the ones from extra parts.

Yup, I have the experience. I converted my headlights to headlights that except H4 light bulbs. In doing so I had to modify the retaining rings. Well those adjuster screws were gummed up and the thin metal holding them snapped as I tried taking them out.

I went to the store, bought some new stainless machine screw and nuts. Fires up the cheap little fluxcore welder and slowly, successfully welded new nuts to those broken tabs.

I've never succeeded in removing those nuts and I've tried. They may have been installed with a special clinching tool or similar that prohibits removal without destruction. It looks to me like the all-nylon replacements sold by Macs (PART #: 66-71084-1) would work if they're the right size.
