Guys at the local installer told me they HATED the Precision gasket but couldn't get anything else and made it work. They also said they have done "hundreds" in their lifetime but hadn't done one of these trucks in a number of years, so it doesn't sound like it's current news on the gaskets either.

This was a shop that's run by two guys for 40 years, so they did a ton of them in the day, and whatever biases were true about glass and gaskets in the 70s and 80s has likely carried over!
