the guys like Bonnewagon and others who were born last century before the Gore invented the internet for us know how much research went into just about anything we did on our cars. I remember blowing the 350 Buick engine in the family wagon. I have never built a Buick engine so I went to the dealer to buy a shop manual whch I actually had to read in order to rebuild the engine. My wife thought it was terrible that I got grease on the expensive book. The only mouse I had back then was the one that sneaked into the garage and the screen I had to look at was on the door to the house......things took time back then and to get things done we had to figure things out on our own but the beer was cheaper.....🙂
