I'll check my original setup tonight. Years ago, I had left the chrome washer alone and re-used, as it wasn't "too bad", condition-wise, but may have literally destroyed the evidence left on everything else, as I wire brushed all of it and shot with Cast Blast (when this paint first appeared on the market). Should have also mentioned that I found the bolts to be a tad shorter in length, used for the safety catch, than the typical latch bolts, fender bolts, etc. (star washer variety). Same head markings, just a wee bit shorter. We had a nice mix of these bolts in the engine compartment with an early car.
