67-68 and 69-72 Differences

[68 TT]

Also note that the 67 wire harness comes through in a different location than the 69. You could probably cut a new opening to use a 69-72 harness in a 67-68 and relocate the wiper switch to the choke hole in your 67-68 dash panel.

If you can find one there are block off plates & plugs that go in the 67-68 choke hole opening to hide the choke lettering and fill the vacant hole that could be put over the left side wiper switch hole when it was moved.

You would still have to label the relocated wiper switch that is now in the choke labeled hole or you could just put a 69-72 dash panel on it instead and have a cleaner look.

I would go with the 69-72 dash panel.

Thanks for all the replies and help. I will have to compare the pictures of the firewall when I get home. Are there Vin markings anywhere on the frame? Someone said maybe on the driveside frame rail by the engine. But don't see anything there?

Top of the frame rail just behind the steering gear box is a partial VIN. It is in 1/4" or so tall letters and will be easy to see once you brush off the grease & dirt in that area.

I'm glad you posted that pic, showing the differences on the firewall. I'd seen one in a recent post, and it also included a pic of a later pedal mounted to an earlier cab. Another thread had detailed how to patch in a replacement panel to be able to make the change...putting the pedal in a '67-8 cab.

The other option for a pedal-actuated brake is to buy the unit from Lokar. That may be what I do, because I already have the brake/accelerator pedals, as well as other pieces. It would save having to jerry-rig the later pedal to the earlier cab or trying to patch in a piece that I don't have...like from a '69-72.

Do you know what year your chassis is? Does it match your cab VIN? You can look on the driver's side frame rail. Here's a pic of my chassis, so maybe you can correlate yours to this one. The bracket on the left lower of the pic is part of the ebrake

The first pic is a 72 showing exit for e-brake cable, second is 67 cable exit.
Third pic shows the small bezel ignition switch (67) only, 4th is a 68 bezel/switch which was used up thru 72. The final pic shows the location of the wiper switch, located above the headlight switch, 67 & 68 used this configuration, but it was dropped in 69 because many people complained of accidently pulling the knob off the wiper switch believing they were pulling the headlight switch to on position. To avoid this confusion, the wiper switch was moved to the opposite side of instrument cluster in 69. Hope this helps. Again, my money is on your cab being a 1967 with little doubt.

I see you're getting plenty of response, that is good, and lots of opinions, lol. My suggestion would be to determine the year of your cab, (probably 67), then go with the parts to a same year cab. This will elliminate any need to jerry-rig, cut, alter, fill, move etc. Many times I've wished for the hand brake instead of foot, mainly because one never forgets to release the hand brake, it's right there in the way so to speak. Also here is the little hump behind the rear-view mirror on 71 ONLY that I mentioned earlier. Hard to see maybe but its there. The second pic is a rare factory auxilary fuel tank switch on a 72 Longhorn barnfind. Good luck with your build!
