Well the next plan of attack on the 55 Crown is the vacuum wipers, in the 13 mile trip home tonight in the rain they cycled 2 times- how can I get them to work better? I'm trying to leave it bone stock rite down to 6 volt & drum manual brakes yet. If I can get it to work as good as it was designed to back in 1955 that would be good enough for me. I can hear a vacuum sound under the dash when switch is on but it doesn't sound like a leak.
