UrS-car Ronals and Movit Big Reds?

[Steve Marinello]

An oft repeated question, but I'm not sure if the answer was ever definitive
for the Movit, or Movit-type, kit:  Will the 16" x 8" Ronals fit over the
Big Reds with/without a small spacer and if a spacer is required, is it only
3-5 mm?

Thanks,

Steve
