I believe there is a rebuilt one on the 'bay right now.
I hated mine, the float would stick open and spray gas all over the engine. No matter how many times I had it apart I couldn't get it to stop that. Also, it was nearly impossible to find smaller main jets for it although I finally did around the time I switched to the Weiand 7503 and the Holley 1850. They were used on Avantis and the Avanti owners group is a source for jets.
