The rollers sit in molded pockets in the underside of the lower turret shell on the M51 - not sure how you would fit that to another tank without cutting the whole pocket out, and then try to get all 3 of them all glued into the upper at the same protrusion height? If one is lower or higher than the others the turret will not sit down flat and you'd probably have it catch even worse?

Thanks Lord Haw-Haw, I now have that scene from the movie stuck in my head - but with Gary's voice saying *it rubs the graphite on the rim, or else it hears the turret click again...*
