You may be correct on 67 through 69. But 70 through 76 a-bodies standard shift with A/C were 3 spd. only. No console with a 3 spd. Some one would have to show me a 4 spd. data plate to prove this to me.
This info came right from a friend who owned and still owns a dodge dealer at that time. I will be asking him about the 67-69 A-bodies. It never concerned me about 67-69.
I had a 70 340 Duster which is still next door. 340 3 spd.. I was going to put the A/C in my Demon. and still might. I was going to have a Data plate reproduced adding the A/C on the Demon until I found out they never made one. It would have been one of none as per this person who I had no reason not to believe.
I researched this for a long time and found none made. Maybe this post will prove my friend wrong and open the door for A/C in the Demon???
please chime in if you have a factory 4 spd. ,A/C, a-body 70-76 with a data plate attached. You would make my day.
