I am trying to find the correct Harrison Radiator for my 59 Chevrolet pickup. The ones that I picked up in a salvage may be correct, but I'm not sure. # one: Description and numbers: Harrison R60 59K 3145860, rubber overflow tube goes down metal channel made into radiator support. 90 degree mounting brackets with 6 holes on each side for mounting to core support.
# two Harrison 11A B59 3135642. 45 degree bends in mounting bracket for mounting to radiator support. Radiator brackets are tapered so radiator sits at slight angle. 3 holes on each side for mounting. Overflow tube is metal with clips holding it to the radiator shell. | | | | | Joined: Mar 2004 Posts: 6,233 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 6,233 | 3135642 = 1955-59 Series 3 (2nd Series) w/ 2" core. I believe B59 is the date code (Feb 1959). I can't find any reference to the other radiator number...could it be out of a GMC???

I believe it to be the original radiator.
