Looking for a cat/gp frame close to Southern California!

Did you check with Franks Pontiac,also good to know if you need a 2door hard top or a sedan.Also someone might know if 61-64 are interchangeable for Cats.We know GPs were all 2DHTs but all Cats were not.Tom

[61-63]

Tom '61-64 Cat 2 dr and 4 dr are interchangeable. Not station wagon. If you look at the dimensions in the chassis manuals the bolt holes are off a little depending upon year to year comparisons but there is enough wiggle room to make it work. It may be necessary to elongate the holes the body mounts fit it a smidgen here or there but you can mount a '61 Catalina on a '64 Cat/GP frame etc., etc. The '61 frame has the rear axle an inch I think it is farther forward than the latter three years.
