What Radiator are you using in your 2-ton trucks? My 1955 6700 Bus has a 1966 327 engine. The radiator might be original, I don’t know. The radiator is stamped Harrison 3133708 and R-13 55D. The core measures 20” high, 23 ¾” wide, and 2 ½” thick. Inlet measures 1 ½” and is in the center. Outlet is 1 ¾” and is on the passenger side. I went to a radiator shop hoping they had something, but they didn’t. I haven’t found any information on the 3133708.
I searched forum posts and found someone use a radiator from LMC.
LMC has one listed 23 ¼ wide for 55-59 @ $399.95 With shipping and tax that’s $500.
