I have a 1963 Buick dynaflow trans from a 63 Riviera for sale. Has a little less than 110,000 miles. Selling with converter, Full rebuild kit, cross member (x-frame), dipstick tube, flex plate, linkage. Make me an offer.
I'm one of the few people who like the Dynaflow, and I like it a lot. I had a 63 Wildcat with one and it was awesome. Good luck selling yours.
