Rusty that is the coolest sounding slant I ever heard. In 1971 my dad had a 62 with a slant 6 push button. He left me take it to a football game.
I was coasting it backward on a hill in neutral holding the throttle to the floor and then pushing in the low gear button. I destroyed the right rear sears snow tire he just put on being able to push the second button while it was still going backward. The J's I put on that hill were enormous. He saw the tire a couple weeks later and I blamed it on my older sister. I don't think he believed me because I never drove it again he bought me a 66 GTO
I would love to take your 66 for a ride it sounds like I could hit drive with yours. Does it have a sure grip?
