I went to the junk yard today (finally warmed up) and measured a 1/2 ton... it looks like the extra deep deep radiator (3") is 3/8-1/2 deeper towards the engine side.. which corresponds with no clearence with fan.
I also looked and could not find any Harrison tags or stampings on radiator.. it looks original and has the correct mounting but could not find and identification... maybe a prior rebuild?
Now probably looking for a new radiator as the junk yard stuff was ... junk. Anyone have any feedback that recently bought one? best cost? quality issues with some?
