I had to laugh about the wiper reference. It made me remember my old '63 Scout and a friends old LR Defender 110, both with vacuum wipers and tiny engines. I once had to pull over about every other exit off the Interstate to wipe off the windshield in a snow storm. It got so bad that a Highway Patrolman noticed me and stopped by to see if I was having any mechanical trouble. He had noted that I kept leaving the highway. I think 1968 was the year that electric wipers were actually mandated, someone was thinking! We sometimes forget how primitive some vehicles were only a few decades ago. The old LR Defender had little manual handles for the wipers like an old army truck. That didn't work well either.
