I do not have the 59-66 blanks John showed above, they are available on EB, but I never found a good price on them.
I had to look around for a while, but I found 3 sets for $9 shipped. I thought that was a good deal.
The issues with the Curtis cutters is the codes I pull off the old key, if it's that bad, may not work.
My keys work... They are a little "fussy" though. One ignition key was cut with the blank not correctly positioned and the key has to be pulled out slightly to work. I have good trunk keys, but it's obvious that I have to do something with the ignition keys... Another direct copy won't be any better.
