I should mention that I did a fair amount of searching, as well as looking at pictures of unrestored cars. Nothing really helpful thus far.
I went thru this a couple of years ago. Like Richard, I reused the 2 small washers and I only had 1 of the large ones. I could not source one, so I made one. Luckily, I measured and recorded the measurements of both washers. Small washer: OD-.633”, ID- .330”, thickness- .030”Large washer: OD-.1.130”, ID- .860”, thickness- .030”This is for the car listed in my signature.Hope this helps a little,John
