The pre-'67 valve body lacks the passage that feeds throttle pressure to the PTK module.

To convert a '62-'65 TF to PTK you need to use a valve body casting from a '67-'68, the later ones won't work because they lack provisions for the pump check valves. With the correct VB casting and the PTK module in hand all you need to do is make a bushing to reduce the diameter of the hole the rooster comb fits in.
