Slant six 904 VB in 727

Compare the rooster comb that operates the neutral safety switch/reverse lamps. They changed over the years(not sure when). Then get the correct Neutral switch to match.I also believe you will loose the part throttle kick down. The 72 year may be when they came around,Not sure of that date too.

I have an early 1972 SB 904 too. Both have the three pin. You bring up a good point that I forgot about with the KD. The gurus will chime in but, I believe all late 3-pin /6 kicked in under heavy throttle. Correct...The SB 72 may or may not have the part down. If it has it, I think they kicked in easier but the guru will know.
