Hey Will, I just lucked out and found one on Ebay for my 46 Burb.
I will have the burb home in several weeks.
The bottom was ripped out of my old tank but every thing else is still there.
I understand that the later model tanks are the same except for the location of the opening location into the tank.
Get back with me in about 3 weeks and I will know more when I get the truck home.
