WTB: 2-spd wiper switch for 65 Olds Cutlass

Just starting restoration of 1965 Olds Cutlass Convertible -- cannot find the 2-speed wiper switch.

OPGI has a replacement 1 speed switch - would like to get original part -- if possible.

I'm new at this -- if there is a good on-line parts place I could go for these kinds of questions, I am open to learning. I have read about Hershey -- is there an on-line equivalent? Really don't want to go shopping for all my needs one time each year

Thanks in advance for any assistance.

Joe
