Sometimes I go down to the shop, drink a few beers, smoke a couple of cigars and just enjoy the atmosphere. This was one of those times.
I did clean the wagon's old distributor cap off as a test, by soaking it in a bucket of cold water and some Dawn dishwashing detergent overnight. It was caked with a 1/8" thick layer of greasy crap.
Turns out it's an original Mopar Forward Look piece.
Also cleaned the Ball & Ball / Carter 1bbl carb that I pulled off the wagon while I was at it. Now it's ready for re-building.
