MUZ, is this just a once or twice used tool? Or do you plan to crank these BJ's out and make some money? The problem with the OTC style kits, is you need 6 pairs of hands to hold all the adapters. The Snap-On BJP1 all locks together. It's a ton more money, but you'll pound them in and out like no tomorrow with it. It also has a flat spot to put in a vice to bring your work piece to the bench.
