Michael and Gary,
I think I found the wiper motor park plunger switch for $14.25
I see one in the Moss Motors catalog (fall issue 2-0310) page 87, item #11 part number 145-630. Make sure you ask them if this is the correct one. there are 2 switches listed. the other one is part number 145-620 which shows no longer availible.
Moss Motors Ph# 1-800-667-7872.
Good hunting,
Steve
