I bought this radiator from eBay to fit in my 1935 Dodge truck (eBay item number:301852127518) and it works great. It evens has trans cooler built in.
Get the total measurements for your truck and see if this one will fit. I installed a fan on the front side, no room with the Chevy 5.3, and I use an adjustable fan
thermostat. It never gets over 185, that's my thermostat setting.
