look up a member named "gaspig" as I recall him doing the nicest '66 restoration I've ever seen. His was a roadster though, not a halfcab. I think there are things nearly impossible to find such as the driver side mirror and rubber boot around the transfer case shifter. Be ready to pay $1,000 for a nice set of '66 hubcaps. Also run a search for the same topic as I recall a very long list of '66 only aspects. Door striker location, keyhole location, bolt pattern along top of windshield, etc... But if you find the thread I mentioned it will have all the unique features.
OK, quickly off the top of my head, these are the 1966 only things I can think of:
Silver upholstery
Eyebrow grille
Metal fresh air box
Single circuit master cylinder
Non detent t-case shifter
Rectangular t-case shift boot
Long tapered dash knobs
Screw on rear view mirror
Logo'd horn button
Pedal rain gutter
Hubcaps
What else?
Where are the real 66 nerds to back me up on this?![]()
A few of the things you mention were only available on the early '66 Broncos.
Here is a good thread about this:
