sorry for delay been recovering after surgery .. the MAXXII is a 1972 I'm told (??) serial number 375 on the plate it has a Rockwell motor and I thought it was quite nice until I discovered it has two large gap cracks running front to back down the underside of the the belly of the tub..
I'm committed to fixing the cracks I just want to do a professional job and don't know the correct way or materials to use, we need 4 tires also ..
any direction is appreciated
thx
