If you go for one from Falcon Enterprises, I would give Ron a call to confirm which one is correct for your bird. He's a nice guy, really knowledgeable and should be able to give you the answers.

It looks like the `64-`65 years have 39" steering shafts so you just need to figure out if you have a 1" or 1-1/8" sector shaft and if the ratio is 16:1 or 19:1.
