Yeah, the 4 speed boot goes on the floor under the sliding gate plates that are part of the console assembly. I bought the boot, too, and was going clip the ears down and laminate to the bottom side of the new console plate. The problem is, the stocker has a depression in the back, that it has a molded in base curve, too.
Not being a wise guy, but you know you need a new plate, right? I think they're like $45 from Muscle factory, the exact same thing as OPG for nearly twice as much. I know they're the same item, I held both in my hands on the same day when I was in SoCal.
My wife is trying to get me to have a leather one made, but I am off to other non-Chevelle projects. The leather one could attach to the recessed walls of the hole in the console with some home-made retainer strips underneath. I found a company that custom makes any boot for $100. I just haven't had time to measure the stuff exactly to fax them the design details.
