Either way its a one year only setup. I dont believe cylinders can be swapped with a different year. Same goes for the entire switch. The plastic ign cover is different too.
If Im mistaken, which is quite possible I would like to see what could/can be done. We have a 67 and 69 cuda. A couple years back someone had the same question...so I tried a spare switch in a spare dash and it was wobbly like a donkey dick...
