67-69 Barracuda differences

Other distinct differences are...

the ignition key switch and mounting are different between all 3 years, and the wiring harness also reflects that.

the glovebox door is also different between 67 and 68/9, it was mandated in 68 that the glovebox have a button latch to keep it closed, 67 did not have this.

the seats are also different between 67 and 68/9. It was also mandated that the front seat backs latch in place for 68/9, in 67 they just folded forward

the dash frame itself also changed from 67 to 68/9. In 68 it was mandated that the top of the frame would be sectioned out for crumple safety, so it is cut out in squares under the top pad. Also the aforementioned key switch area is different every year.

the speedometer cable mount changed in 68 to the clip on style, in 67 it was a screw on.

Yes, the idler arm has a pass through bolt in 67, so the K frame has 2 ears, in 68 that was changed to the modern tie rod end style and one bolt.

should we go into the differences in the 67 trans and 273 rear crank register as opposed to the 68 and later 318/340/360? That will frustrate most swaps between early and late motors/transmissions.
