New member and Radiator question?

[Jyman]

Ok I have been lurking for a couple years, and I guess it was time to join the community. ok a little about my truck. Its a 1948 chevy sitting on a 95 s-10 frame, It has a 305 sbc with a NV3500 trans and a 3.73 rear with disk brakes all around. I have only about $800 into the truck after parting out the S10. its been a 2-3 year project of collecting parts for next to nothing.

Im at the point of starting to mount the motor and was starting to wonder about the Radiator. I have seen a lot of people use the 19 X 22 rad off ebay. and was wondering to my self if anyone knows of 19 X 22 rad that came in a car or truck that was stock?
