The one OldMiniBikes sells is a Azusa one that design to weld to the side of the frame rail, It will work but if your worried about being original. Its not the correct way that Rupp did it. They mounted under the engine pan with the front engine bolt. Brandt sell them, but I think someone told me there around 60 bucks from him.
wow, thanks Dude I knew you would know .I rebuilt the motor that came on my green scrambler and painted the bike with rusto -Metallic blue.Looks great .We honed the cylinder wall , couldn't get all the marks off it but alot better than it was.Runs great now took 5000 off the walls with the hone.
