After much time and research – ebay, three wheeler club(s), forums, and Google searches. I found some sources that have been good to me.
I found a guy, Lance, that has a boat load of old vintage parts, pieces, and motors, you name it he has got it. He sold me the Mags, I didn’t really need them, but for the uniqueness of the bike, I did. A pretty penny later, tubes, and the money to have him switch the tires over for me, it is coming together.
