Here is part of a email from Stumpy,
"You and the rest are correct, the shock mounts on the M-II's are stagered. Driver side is BEHIND the axle, passenger side is in FRONT of the axle. This set was designed to cunfuse whoever might try to copy them, lol. On the SSM bars, mine are different, if you look the only similarities are that they both bolt to the spring using the axle u-bolts. The rear springs on these cars are so short you would not have any advantage to adding those " universal" type traction bars to these cars. Mine are also longer then the SSM to get the full amount of leverage i could get."
He seams to be on top of things and has a well designed product that a bunch of us can't wait to get our hands on.
