Old radiator shot, thinking about Jeg's Universal Aluminum, any one done this?

[Old Yeller 1970]

Well, the original radiator after 36 years and sitting on the shop floor empty for too long has finally given out. I've had it repaired once already and it still leaks. I think it would be foolish to trust a brand new $3000 engine to it.

I need a radiator with more cooling capacity than the original 3 row that was in Old Yeller. It didn't keep the engine cool at high RPM's and heavy loads when it was stock. Now that I have the engine in the sig a 3 row isn't going to cut it.

I bought a 4 row brass/copper from Radiator Doctor. They said it was a direct replacement but it isn't because the brackets aren't big enough. So I figured since I'm going to have to modify the brackets I'd rather lighten things up and take advantage of the extra cooling of a 31x19 aluminum radiator.

Jeg's has a Be Cool AL radiator that is a direct fit but $500 is out of the question. They have a universal 31x19 Aluminum radiator for $179.99 and I wondered if anyone has tried it or one like it in our trucks?
