This would be a closer fit. I also like that it has larger trans ports

Only drawback is the cores. this one is a 3 row core. I'm sure we can find one that has the 4 row core and the larger ports.

I've got my stock radiator laying here, it's a 3row copper/brass, I've checked all the local shops to see if they could get a 4 row core, all said no...

The one I posted showed to be a 4 row core, but I didn't look at the hose bibs or fitting sizes.

I would think the size would make up for a row. 28" vs 34"

Got the OE radiator installed.
Put the aluminum rad in the box that the oriellys unit came in. Sealed it up.
Checked all fluid levels then also remembered that the WW reservoir was leaking.
Removed it from under the battery.
I must have jiggled enough compknents that the pump grommet stopped leaking.
I thought sure it would be a cracked tank so one of those will be here tomorrow. Its suppose to have all the grommets with it.
For $55.00 guess I’ll poke a new reservoir at it.

Yeah, I didn't look at the overall size. we would need to measure ours to see which one fits best. I would assume the larger one.

Honestly for core rows, I can see where the difference between 3 and 4 could be negligible on cooling performance, being more are stacked and more air flow would be needed to cool. our rigs already have more stacked in there with the condenser and oil coolers. it might not make that much difference between the two or might actually hinder the cooling performance with the 4th core. I'm no expert but there would be a point were more rows could cause cooling issues.
