Headlight adjust screws on my '41 coupe are frozen. Multiple applications of Gibson's and Liquid Wrench, to no avail. Also I can find no replacement screws on any of the usual sites.
ACE Hardware has hard to find screws. Is there a way you could apply heat to those screws without doing damage to surrounding area?
Know anyone who has a small induction heater?
Wonder if you could make one? https://www.youtube.com/watch?v=vV-dweGKPt0
You might have to drill and tap right through the head of the frozen screw.
Then install a new brass or stainless screw.
