I bought a AFCO aluminum radiator in 2009 for my '37. Don't remember the price off hand, but it was way less then they sell for now. It has worked great up until last year when it started seeping at the lower right corner. This radiator and I am sure the cheaper ones you are looking at are glued together. This means there is very little you can do to repair them if needed, truly a one and done. I bought some super sticky epoxy and managed to stop the leak for now, if a get another year out of it I will be happy, but at some point I will have to replace it. I cannot see spending $800 or more for a truck that may only go a 1000 miles a year. If the new one last another 10 years, I am good with that.
