neutral safety switch test

I swapped out a 74 904 for the push button trans that was in my car. Is it fine to swap out the one prong nss originally from the car and put into the 74 904? Should work fine right?

If I remember correctly the three terminal switch and the single terminal do not exchange.
I think one of the differences is the length, and the other is the comb in the trans is different so the switch isn't operated correctly.
