Phil, quite frankly, your washers are WAY too big O.D. I bought them and can't understand how they would be so BIG on the Outside Diameter? My originals are perhaps 5/8's inch OD / 3/8's I.D........your's are 1 1/8th OD....still with the same I.D.
I'm sure they wouldn't "protrude" outside my comb......but why NOT a SMALLER O.D. ? I'm sure it doesn't matter ......."technically"....but ..."cosmeticaly" I won't USE them .
My last washers were 1" OD and there were several comb hardware styles that have the post inset into the stock and the 1" spacer would "fall in" so I had this batch made with wider OD for this reason only.
If you give your address I will send you some that are 3/4 OD -They are different colors if that matters.
