Well "sort of." When I had the old 70 440-6 car, I thought the shifter might be getting a bit worn. This was the factory issue pistol grip, the shifter slides/ locks/ clips into the shifter and there is a little rubber in there I think.
The comp plus had a bolt on lever
The competition plus had some differences........
Levers.........Levers are not interchangeable between factory and CS. The factory had no bushings as I recall, or at least the rods/ bushings from the CS will not fit the OEM
The reason that I tried to swap levers I DO REMEMBER. The CS levers had some play where they fit the transmission shift shafts. I used to cut short pieces of feeler gauge and jam in there to take up the play. I remember well that the OEM levers HAD NO play
Without the feeler gauge shims, there was NOTICEABLE play front/ rear in the lever. Poor quality control!!!
(I was around 24 years old on a side note, this was about 72--73)
Bushings........either the factory had no bushings on the rods, or they were different size, been 40 years LOL
Rods "ends" are different size, IE will not fit the levers/ bushings between one / other
I don't remember, but I do not think the OEM had the adjustable shift stop bolts.
