Had to replace the headlight bulb today and found that I could not adjust the lens to make the FORD be on top on the right one. I took off the left side to compare and found that rings are differant inside. Is this normal and where do I find the right one to match the one on the left?
The Ford ring with the simple clip is for the round plain glass lens, '15-'21, or any aftermarket 8 1/4" dia round lens.
The other ring with long clip with 2 fingers is Ford 21-27 and it is for only the Ford 'H' lens.
PM me, might have a good enough 'H' rim for trade with you.
Looking at the retaining pin in your bottom picture makes me think they need some reconditioning before you loose a rim & lens.
I would suggest a little Crown Royal might make them appear "just fine".
