I have a Model A street rod registered as a 1930 but it came with a manually operated windshield wiper. I want to convert it to an original Trico electric wiper system but am a little confused about what modifications I need to do. I just bought a chrome 6V electric unit that I assume installs somehow into the inside of the upper windshield frame which is a tilting frame. I will use a voltage converter so as not to burn it up. I would appreciate any photos of a similar unit installed to help me figure out how the installation should be done. It almost looks like I may have to cut away a small part of the header panel to get clearance for the new unit. Photos or instructions will be very helpful. Last thing I want to do is butcher my car. Any help will be greatly appreciated.
