The washer bottle, wiper motor, antenna, antenna switch and thermostatic heater control were supplied by the same manufacturer, Trico.

I've seen many units replaced with electric wiper motors, but that kinda wrecks the whole system as you lose the spray coordinator and the spritz system, itself.

The thing that frustrates people the most is that they don't know that their system is not working up to snuff due to a bad vacuum pump diaphragm or check valves. Vacuum leaks in the antenna switch, wiper selector switch and thermostat are cumulative leading to wimpy operation. While the opposite, it's like blowing up a ballon with a pinhole in it.

I must have done that 15 years ago and I just noticed a flaw. I have the distributor getting vacuum from the manifold tap when both vacuum motors are controlled by carb vacuum taps.

I'm comparing your diagram to Lowell Domholdt's detailed description of the vacuum and water lines and "T"s in his write-up of the system, I believe there's a difference. Will get back on this soon - got some grandson football to go watch.
