I`ll add a quick note, of the 3 St Louis built ( G in the VIN) 71`s i`ve owned, 2 of them had build sheets on top of the gas tank, the current one i`m doing is a Los Angeles build and did not which is too bad as the top of the tank looked like it was brand new.
Take the time to drop the tank and check.
