Proud of ya but I think wiper blades are the least of your worries. Fortunately all including the pan can be replaced quite easily these days. I snagged an ole 77 buried in mud in Illinois in the mid 80s with the 2F gas engine and it fired up after giving it a once over and it sat for three summers he said! They are great machines! I've owned two others since and could tell stories on all of them!
the only thing better than that awesome LC that can go anywhere is your style of making videos... "custom ventilation holes... ::cutscene:: the birdsnest is along for the ride... ::cutscene:: is that a flowmaster?? ...." LOL
