Well, after 43 years, the original vinyl perforated seat bottom for the driver's seat has finally ripped. While vacuuming, I pushed on the seat too much getting up and the seat bottom ripped. Pretty tough interior to last 43 years! Luckily, a local member here in Michigan has a 75' Black Cloth interior available, so it should be a straight forward bolt in. I get to pick it up this weekend and install it! (Thank You Gary Antoinette, and Dick Baumhauer for sending me an e-mail to Gary's Craigslist ad!)
