I recently purchased a 66 convertible A code 4 speed, but the car came without a washer pump, resevoir, etc. Can someone send a photo of a correct setup for 1966 to me? ..I can imagine this was an option...???
Two speed windshield washer is standard on a 66. NOS pumps show up on ebay occasionally. Reproduction pumps are junk IMHO. Reproduction resevoir bags are ok. Don't think I have a picture handy but will look.
I purchased and installed a reproduction pump a number of years ago, and it still works perfectly. Perhaps you just got a bad one...
At any rate, this raises a issue I've wondered about myself for a while: some washer bag brackets are screwed to the fender wall and some are spot welded. I'm not sure which is correct. Mine is an August '66 car and has its bracket spot welded in place. Oddly enough though, it got the white-lettered washer bag rather than the gold-lettered '67 version that many late production '66 models received.
Hopefully, I was able to muddy up some issues that you may not have even had!
