Found some Panhead Key Blanks. Obviously small "42" key is for saddlebags. Which key is for ignition and which is for fork lock?

Both keys are same style, but one has a round head and the other has an Octagonal Head.

 

My 68 has a round key for the forks. The ignition had been replaced when I got it. On years 48 to 63 the ignition lock had no tumblers so any steering lock key would work. In 1964 they went back to the earlier switch with tumblers and you needed two separate keys from 64 to 68.
