/6 to 360 rad swap

[Madhatter1776]

I am swapping my /6 to 360 in my 75 duster, from looking and reading on this site I new I had to change rads so I ordered an Spectra Rad to go with my swap, my question is when installing the rad, do I have to make any mods?, the Spectra I have does not seem to fit right in, is it possible that I have the wrong rad out of the box? thanks a bunch in advanced

I don't know about spectra rads, but I did the same swap in my 74 duster and used a champion rad and it fit right in just had to drill one hole

I bought a stock looking high efficiency 4 row that bolted right into my '68 from US Radiator. The quality is top shelf. I never liked the look of an aluminum radiator in these old Mopars.
