I have started working on my 71 Pinto, 1.6L, and it looks like I will need a new radiator, due to too much corrosion. In looking up radiators, there are not many out there, and the ones that I could find are very expensive. Are there any other cars of that era, or more modern that I can use? I heard that some Mustangs are interchangeabl e, but I only found info on the 74 Pintos and V8's. Any help would be appreciated!
