Surely the bolt pattern on these casters isn't exclusive to Snap On? I have a KRSC430 and want to at least upgrade the pair of rigid casters to swivel so I can move the cart around in our cramped shop without doing the Austin Powers thing.
$116 for a pair from $nap On.

I like the softer skateboard wheel type casters because they go over bumps easily and don't get hung up on zip ties and such.
