Looks neat! You should orient the key slot vertically inside the steer head so it looks more like the original dividing line. Cool, though!
Yep, will do that, this is just a mock up, to see if I would like it, and I do. Once finished it should look really nice.
I am using the front grille ornament from my 70 Mav, and attaching it to an aftermarket locking gas cap. The grill ornament does come apart so that makes it a little easier.
I have had good luck with JB Weld, so I will give that a try. 3M panel bond would be another choice, If I can manage it, I want to try a screw of some type as the main connector.
