Hi Jay,
I have an Autopower bar in my '68, but as already said, that's a high windshield car and for a '67, you need a low windshield bar.
I think you have to go custom as others have said. I can't be sure if there are factory holes for a bar in the early cars (pre '68) as there are for the later cars ('68-'70). Heck I don't know if there was a factory bar for the early cars and good luck finding one.
Making it fit with the top installed will take some fabricating skill. My Autopower does work with the top but it scrapes on the bar...no room for a bar cover, and mostly I go without the top. It's a fair weather driver!
