I went to the local hole in the wall radiator shop to have my cleaned. It had too many high pressure holes in it and it would have cost a leg and an arm to have everyone of them fixed. Some old guy walked in the room from the back and said "that is the same radiator out of an 84 Olds Diesel". He told me to hold on and he came out with an identical one ready to go. $90.00. Same size, same core, same row, same size fittings, same everything. Bolted right up. I'm not running 15 degrees cooler than I had been.
Regardless if he was correct or incorrect as to what it came out of, it's the same radiator.
