In my project thread
http://forums.sohc4.net/index.php?topic=69058.0 I am building a bobber out of a basket case 750. I am currently working on the carbs (6547A) and I have found rebuild kits and the connector o-rings, but some other parts are not so obvious and I am not sure if I can get a bushing or if I need the whole part. The carbs were nasty and spray bombed, but I enjoy resurrecting stuff like, when it can be done.
