Hi my name is sal .. I'm a little confused as to which heater belongs in my 1953 chevy 3100 .. I purchased a Harrison heater that bolts to the kick panel but I noticed that some trucks have the round drum looking ones ... The guy that sold it to me he's truck is a 51 and mine is a 53 ...the heater box that I bought does not have the little door in front for recirculating ... But my fire wall has all the holes already there .. But just not sure if it should be the round one or the one that bolts to kick panel and if I should have that little door that opens for recirculating ? Thxs sal
