To add a little more info to this project.

A local auto parts store can get me a 2 row copper and brass radiator for $265. They say that todays 2 row are as good as the older 4 row radiators.

Anyone else agree with that?

Two rows in aluminum is way better than two row in coppper! The reason is that the core tubes are wider. Most aluminum radiators for heavy trucks is only two row but measure the same as a four row in copper. If you have a "cross flow" then the number you need for a "P-30 motorhome cassis" not a bread truck is 431338 from ready-rad. This is aluminum and plastic cross flow with a remote fill cap (cap not on the tank directly).

Yes, The cap is on a short hose connected on the front. I looked up the number above. The measurements are an inch smaller in both directions. Im sure I can still make that work.

I found ready-rad at some different suppliers for different prices. Do you recommend anyone to buy from?

An radiator seller in OR tells me the newer radiators with 2 rows have wider tubes in them. They 2 1" tubes where mine has 4 1/2" tubes. The total tube width is the same as long as the core is 2+" thick.

I got mine new from my local Carquest store but I did have to find my own number for it cause they kept finding radiators for bread trucks! I still have my old good one here and measured it.. it is 29 inches wide and 21 inches tall and this is at the flanges where the tanks are attached. Inlet hose-top left/outlet hose-bottom right/hose for heater return-top right rear side/hose for cap-top right front side. My coach was a 1993 Southwind "P" chassis, hope this helps
