Radiator questions

[Tomsriv]

So I took my radiator down to the shop to get a pinhole leak fixed. They told me that the core was leaking in several places. They could fix it for $45 but to do it right I will need a new core. For $320!, plus labor to put the tanks on. I checked my repair records and this radiator was last re-cored 15 years ago, and the fins are starting to disintegrate, so I would say its time for another. Darnit! I didn't plan on spending my government rebate check on a radiator! Most of the repo truck places want $400 plus for a radiator and Summit has a Griffin aluminum available for $457.

What should I go with? Also, this had a 4-row, but this is a 1/2 ton, short bed stepside with no AC, so I won't be putting that much load on it, even with a full bed. It has a healthy 350 V8, but I think a 4 row might be overkill. What do you think?

In addition, the Griffin radiator that is supposed to fit my truck has a 1.5" inlet and a 1.75 outlet. My current radiator has 1.75 for both. It measures about 22x25. Does that sound like the stock radiator?
