Probably will not see many 73 Chevy trucks as I bought a brand new one and kept pretty good care of it and it still rusted out just in front of the rear fenders at and also the rear of the front fenders ... I and 3 other guys back then bought brand new trucks, all 1973 Chevy and GMC..
Right away my wiper switch did not work and the other two guys had the same problem and when we all three got new ones from the dealer they did the same thing ,,came on when ever they wanted and stopped when ever they wanted..
I finally put a toggow switch on the bottom of the dash board ,,,and it was that way when I sold it ..Curious if any of you had this problem or did General Motors fix by the new 74 's came out?

this it the 73 truck in this photo ,,the wife had the Camaro .
