Bad news, Terry. I checked with Harold and he told me he got the basic dragster chassis as a partially-built unit in a lot of several built-ups. He has no idea where the axle came from.
He was trying to figure out what to do with the gluebomb dragster and the resin Ford wagon he had also purchased, when the Mooneyes Drag Team idea came to him. So, bottom line: he doesn't know the source of the front axle.
No help here. Sorry!
