I am posting this here as these are probably the engines most frequently found in the cars I am talking about.
There's this place about 2.5 hours east of Toronto called Minakers. It's a wrecking yard that has been accumulating vehicles since the 30s. They have decided to close, and are sending all 3,700 vehicles to the crusher. ALL OF THEM! There are a quite a few 60s and 70s Cadillacs (some older). Some of them are relatively complete and virtually all of them still have engines.
I wanted to let everyone know so that they could attempt to rescue as much as possible.
Getting glass out is easy enough, you'll get the hang of it quickly. Take a piece of piano wire (after you remove the molding around the glass) and push it through the caulk. Grab both ends of the wire, maybe wrap it around 2 screwdrivers or 2 vice grips. Saw back and forth. Good luck!
