Sounds close to what I did with my chrome top. I bought this one cause my Team Magic has no replacement pulleys in existence. I'm waiting for my Losi box also. With the chrome top, it came with some adhesive backed rubber pads. I put those front/back of the rubber wheel. It's the only thing to hold my truggy in place. Been using it for the 8 and 8T. Two GP 3300 batteries here.
