I recently acquired a project that seems to be a somewhat odd one when it comes to selecting parts. This 1944 unstyled AR is in the narrow SN range where changes were made being SN 263652. I am needing to locate a radiator core and the parts diagram I look at shows it having an AA2235R. Many online parts suppliers are showing their core will replace part number AA2235R and AA5582R as well, and is for styled AR tractors above SN 260000 with the core top & bottom plate being 18 inches wide. My old core is 18 wide on the rear, but 18 3/8 wide in front which appears to be AA5582R used on 60, 620, 630's. I have found suppliers that advertise the AA5582R core being 18 3/8 wide. Not sure if mine is the same as the 60,620,630? Can anyone help me verify??
I have a 60 tore apart in my garage right now. It measures 18-1/2" across the front outside of the radiator frames. The core itself is much narrower, 16-3/4". The only p/n I can see is A2369R, but I believe that's the number for the side frames themselves, not the core or the complete radiator.
