I used a PRC radiator in my 48 truck and 56 Chevy, added the shroud and Spal fan to my order as well. They are made in Indiana and are good pieces. The 56 was for an LS so they mounted the inlets on the right side tank in the crossflow radiator and added the steam vent. I had a question about the install on the 56 and the company was quick to answer. We had the 56 on HRPT last year idling in traffic for hours with no over heating issues. The only issue I didn't like was the need to drill mounting holes in the brackets. And that can be a plus for mounting where needed. I will use the same in my Burb.
