I should call it "The Rum Runner" since many parts came from Panama? To fit a magneto you must clearance the relay boss, front cylinder and cooling fins on the front head. My pistons weren't coming high-enough in my bore(low compression), so I had McFarland turn some off the base.
This is better !
These are NOS S&S Pistons I've been saving (+.010)
I sanded off the edges and rough spots . . .
