I have the same setup as yours in my 1965 Pickup. Sorry I don't have any pics but I will try and describe it. I am still using the original pedal and rod. I took the pivot that mounts off the side of the block on the older 6 cyls and mounted it flat behind the carb linkage. To do this, we made up a plate to go across the back of the carb (parallel to the valve cover) and picked up the two rear carb mounting bolts and left a little hanging out towards the firewall side. Drill a 3/8" hole in this plate so as when the pivot point is aligned with this hole and the one arm is aligned with the carb linkage. Put a 3/8" bolt thru the hole and slide the pivot over it with a double lock not. I believe I had to use a couple of flat washers to keep the height correct to remove any bind from the rods.We also put a small plate on its side welded to the top to prevent any flex in the bracket. All that is left to do is make up an arm from your pedal to the one side of the pivot and then a shorter arm to the carb. I had some 1/4' rod that I just tapped to 1/4-28 NF thread and used the swivels from the original. Just open the throttle all the way up and then measure for your short rod. I have put about 2000 miles on this setup with no problems and I like the pedal feel, no rough spots. Don't forget the double return springs. Send me a PM if you have any other questions and I will try and get a picture of it.
