Heater controls on 68 rally dash

I know theres a few differences in the bezels vs the gage housings from 67 to 69. I have a 67 barracuda and a 69 barracuda. Its best to use the metal gage cluster housing and dash board plastic bezels that go with the same year metal dash frame your working with, otherwise some stuff just doesnt line up. 67 has a lot of one year only stuff. The changes they made as far as screw location and mounting in 1968 remained for 1969.
