1972 340 Radiator Part # Controversy

Many radiators have the same part number for automatic or 4-speed with plugs in the holes that the trans lines would normally go into. My book lists 036 as a 340 auto or manual, also listed is the 034 auto or manual and 318-340. I wouldn't worry about it, by 72 things were going nuts anyway...

I'm not that worried, I'm just trying to document what is still original as I disassemble. What book?
