My son just came across a 69 TX2 in pretty good shape but it has a few flaws...we put a new starter pull on it and she runs fine...till the prime burns off... then on further inspection we could see the tank rusting from the inside out...pulled tank and dump a ton of rusty sludge out of it so looking for a good tank or a new tank would be better...do any frame, tanks, or seat parts still exist?
