Hello, Can anyone tell me what the screw size Is for attaching the chrome rim for the tailight lens’s. I found the wrong size In my backup light rim, which I finished repairing.
The “Type A” tail/stop/backup light assembly was used 1924 thru 1930, although some of the individual light bezels differ. As I recall, the screws are 4-40 (#4, 40 threads per inch), and the length required varies with the bezel. For most, about 5/8 to 3/4 inch length will work. The screws are slotted, oval head, countersunk.
I was able to find a small package of military surplus screws in stainless steel, which, after a couple of seconds on the buffer, look very good with either nickel or chrome bezels.
