Well I found out this radiator will fit my '59 f100 without much modification. Move the mounting ears backward, a bit of trimming and drill new mount holes, that's it! Looks like it may even take the stock hoses. Keep in mind this will be a daily driver and will be expected to tow a small 5th wheel. Big rad is a prerequisite

But what to do about the cap? Stock on these trucks is 7psi and the 75-85 E vans take a 13psi. Should I split the difference or go with a 13? I already have a 195 T stat installed.
