Like Crash has said a bit different. My first S&N Chassis was the 16th made, and is pretty similar to my current one but a bit different. The inverted link setup is virtually the same mounting location on the skid. The main differences is where the skid is positioned in the wheelbase. The old chassis the middle of the skid was exactly dead center of the wheelbase(103"WB). The new chassis the skid is a bit forward(109"WB). Both skids are pretty similar but there are slight differences. Trevors was very early in S&Ns years so things may have been different. Would be interested in seeing Trevors setup to compare.
