I am planning on being there but not sure I’ll need to spend any nights away from home at this point. What motel? Not staying at the casino or wherever there’s a discounted rate for the event?
I don’t believe those numbers mean anything to help further answer your questions. You’ll find similar on all of the stamped sheet metal chassis and body parts.
If you need these for your ‘66 they would be 1 year only with the valve stem clearance. @marty mopar
The ones without the valve stem clearance would actually be 1967 through 1969.
I’m sorry you guys, my condolences from the Motor City. I can relate. I just lost my dad in February. Even if you see it on the horizon it’s still one of the hardest things.
