It is as far I can tell really a variable speed switch. Will match your wiper motor since is the actual assembly on my 74.

I installed a 71 variable switch on my 74 which originally was 2 speds. Changed all the linkage, motor and switch. Got as a PRESENT a 71 variable switch on the Rallye cluster I bought ( also changed from standard to Rallye cluster ) and decided to use the 71 variable switch instead the 72/74 3 speeds I also got. Found the plastic plugs from a 71 Coronet donor and VOILA!
