Using the F5 ignition switch. Has 2 flats on it for anti rotation, but I have a round hole. Tightened it down as tight as I dare, already pulling at and stretching the leather. Suspect there's a tang washer out there with the 2 flats in it, but I dont have / haven't found / never seen one.
Did some searching, but all the posts are from like 7 years ago.
Cant add metal behind the dash to make the flats, already almost too deep.
Short of JBWeld... any ideas? Know where I can buy that special tang washer? I'll even replace the switch if needed... they aren't that expensive.
Thanks.
