I have a napa 2 core copper/brass radiator in mine, listed as heavy duty v8 with A/C. https://www.napaonline.com/en/p/NRS3508
Sorry, I didn't notice correction on 22 inch, but you get the general idea.
The volare in question, is a 318 26 inch radiator. I was saying last year I was able to find oem rad for my slants, 71 duster and 79 volare. I could not find a 26 rad. for the 76 volare anywhere in oem brass/copper, not even NAPA.
