There is a 64 Convertible project car with AC for 7K listed in our August 1963/64 Cadillac Chapter Newsletter. Click Here to link to the newsletter and scroll to end to the classifieds section.
This just popped up if you are still looking
thank you but no A/C
This is in Washington State. Be prepared: what keeps this state together is mold, water, and rust.
I do own a 1964 Deville convertable with factory bucket seats. It does have ac. Not hooked up, but a NOS compressor. This is not a restoration vehicle, but almost done. I have $83,000 in receipts, $28,000. Jon
