2brindles,

Welcome to the site. I found these diagrams the other day...maybe they will help. It's interesting to me that you call your '64 an "old truck". To me, it's a new truck. When I was in high school, I had a '38 Chevy car and the Chevrolet showroom was displaying '64 cars and trucks! As they say, it's all relative. smile
