Member here has them. Believe it or not I got schooled on them at Carlisle. There are like 6 different blanks. Two hours of lock talk. Guy knows his stuff. Warren? C body guy
I still have a Curtis key machine that I brought home from the auto parts store with many of the blanks. I have most of the Mopar blanks in case I need them later. Oh, Good Morning Mopar Mad Men.....
