Stop in for a cup of coffee

Those are same as mine. I got blanks from member @gunbunny at Carlisle. I think $5 a pair. I got mine cut at Ace. He can cut them too, but did not have machine there.
If you need keys, let me know what you need.
The 64-66 trunk keys are unique. They have a flat side and a grooved side.
The 67 trunk keys are odd too. But you can use a 68-up trunk key on those, but you can't use a 67 on older. The grove is longer on the 68-up. It's okay for it to be longer, it just can't be shorter.
To muck things up, Chrysler used a trunk lock set that could cover 64 and up all years. All they did was add several levers to adapt to what you needed. There was also the fact that they were pricey. You would pay $10 for a trunk lock for a car that worth $100. No one was doing that. I've seen a lot of incorrect cylinders out there. So I like to see what you got to get you the right thing.
The ignition are all pretty much the same. The heads look different. The square head ignition key was used on most cars that that thad the ignition switch on the dash, the pentastar keys were for column ignition. The thing is, if you were to buy a car and wanted a spare key, the parts dept would likely have the pentastar key blank. The square blank cost .75¢ and the other was only .25¢
I can cut your keys if you want to send me a key your not afraid to mail. No extra charge, I'd cut them at Carlisle and Mopar Nats if i could get electricity. I don't want to run a loud generator and I need at least 20amps for the cutter.
But the price for the correct 64-66 Mopar NOS keys is more than $5. I do have ilco keys that work and I have the colored aluminum keys too.
Oh, BTW fun fact, the pentastar was first used on keys in 1964. I had a guy accuse me of trying to rip him off because he wanted the correct key for his 63 Dart. He refused to believe me when I told him he didn't have an original key. I have those forward look alum keys, but they're pricey.
