Have found that Skoda won't supply the ARB bushes without a whole ARB (at £90ish).

Powerflex do aftermarket bushes but there are 9 different sizes available for an Octy from 19.6mm to 24mm. Have asked Powerflex but they don't know what I'll need.

Car is a Scout TDi PD.

thanks for any help

The reason that they are only sold as part of the ARB is because they are fused to it. The only way to get the bushes out would be to tear them out.
