55.2-59 '59 Electric wiper motor switch

[Tod59]

Hi Everyone,

This question is regarding my '59 Chevy 3100 (what I believe to be) original 2 speed electric wiper motor & switch. My entire wiper motor and system is in place and connected under the dash. However, someone in the past broke off the two metal "tabs" on the back of my 2 speed dash switch.

Question:
Will another 1950's or even 1960's 2 speed switch work in place of my broken switch? Most ads on E*bay offering late car 1950's switch's have 3 "tabs" which I assume is for the windshield washer (which I do not have on my truck). For clarification, my wiper switch does not have the long cable system attached as I've seen in several aftermarket catalogs.

Will a 2 speed 3 prong switch work in place of my original 2 speed 2 prong switch?

Thanks,
Tod59
