Thanks for your reply, learning more about what I need every day. I have a pic of one from one of these trucks and it used a bolt on flange on the rear, have been told both were used. One fellow told me the flange one was used on 4 speed cars, I'm not sure. He's sending me a couple more pics of his trans and shifter I hope. Can't quite visualize how that dash shifter would work with two cables. If i used an earlier one they all had the trans park brake due to the Lockheed rear brakes and taper axle rear end. The truck currently has a Poly and single cable shifter trans in it. My plan B would be to maybe leave the single cable shifter in the dash and look into a 66 trans, are they single cable? Probably slip yoke too.
