The radiator I pictured above has no numbers, just Harrison, and Craig manufacturing on the side. It is 25 1/2" wide side to side, and 22 1/2" tall top to bottom, vertical fins.
I have another radiator that came out of a 61 I think, butit isnt rebuilt like this one and feels like its half full of mud. It has a small nameplate on it that has numbers like you listed. As you can see in the pic is has a different shape, and is also vertical fins. Its measurements are 25 1/2" top to bottom and 23" wide. These are all full radiator measurements, not fins.
Shoot, in Tyler? I'd bring this thing to you one day man. Nice little roadtrip, I can make it to Tyler in about 3 hours. lemme know what you find out
