Having a hard time finding a Radiator for 1964 Jetstar 88 anyone have a lead or ideas on where I can find one?

 

The problem with the J88 is that it has a lot of one-year-only parts. I'd be surprised if you can find a replacement radiator for it. Your best bet is to have your original recored. Of course, old-time radiator shops are hard to find these days, also.
