The Pivot socket is just the thing that goes on the carbon fiber "foot ball" shaped piece right? But on the carpet knife you have to cut the pivot socket down on the sides so it clears the battary and motor. And the pivot balls are just the same as the pivot balls that came with my carpet knife right? They're about 1/4" in diameter? The pivot balls that came with the carpet knife are the same as the pivot balls that I got to convert my car to speed merchent side links.
So I'm considering doing the conversion for my carpet knife. But I want to give the car more of a chance, I'm waiting for some nice new battaries to come in and once I get the new battaries and the new carpet comes, than I'll work with the car a lot more to get it working better. Thanks for the help.
