Not a fan of the straight axle on this body style. Maybe a 64 or 65 perhaps. I own a 66 myself and knew it was not the look I wanted for this body style. Although I do want it to be somewhat period correct. My Dad is in the process of making the straight axle swap on his '55 Chevy and I'm stoked ! Call me closed minded, but that looks just belongs on those cars. That's how they were done back in the day.
