I was finally able to get some time and try my hand at some newly inspired gasket making. My Lang Gasket punch set arrived this afternoon but the 5/16” punch wasn’t manufactured quite right so I’ll be calling them Monday for a replacement. In the meantime I used the 30.06 Hornady shell which I had found to be a great fit for the 5/16” bolts. It was a fraction smaller hole than the 5/16” punch which meant I really had to be precise. I really appreciate everyone’s input and it was great fun learning gasket making. It’s one more way I was able to make my coupe really personal for me. The gasket I cut is below the water jacket in the 2nd photo below: Sent from my iPhone using H.A.M.B.
