if I recall correctly that style blank was replaced with the later style - I don't know which type of old is the same as the newer type... Actually come to think of it, I got a couple of those in from my wife's grandfathers' "junk" stash... now I need to look for them!!
EDIT:
Found them! how do I tell which style they are?
Mine are the old brass GM/Briggs and Stratton keys. They have the mostly oval head, not the octagon head.

hmm, if this is correct, then I probably have what you're looking for.
Quote:
"GM used the same key blank groove configuration for both the ignition and trunk / glove box from 1935 to 1966. Starting in 1967, in an effort to combat auto theft, they change the groove configuration on both the ignition and the trunk to be separate grooving. To add to that, they also added a letter code to designate each of the key blanks. ..."
that image you showed, I have a brass version of the "pear" key on the right.

I would expect if the slots in the key allows the key to slide into the lock, the edge can be cut to match your key/lock. The locks and ignition on my 61 Impala use the same key. Same goes for my 58 Yeoman.
Comparing my 65 keys to the 67. 65 has same sized slots front and back.
Though not super apparent, 67 trunk has a larger slot (red arrow) on the front and backside compared to the ignition.
I learn something new everyday here...
Somebody lost the original ignition key for the 65 hence the DL replacement, the trunk key still has the knockout and code. Look how worn those 65 keys are, near worn out. The 67's have only 43000 and were put away when I got the car.
notice how those 1967 keys have A & B stamped codes - that aligns with the information I found!
