depends what clocks you are putting into your dash, as if you have a squishy" dash then any clocks will have the " sunken effect" and so no radius probs on the clocks / dials,
As for the 19mm radius on the under side, Ash & i were discussing this the other day & basically the 19mm radius needs to go under ( out of sight) & = a 38mm total radius,
or use a squishy dash & carry the foam/flock right under so that no sharp edges can be felt under the dash.
hope that makes sense ?
by the way ...if free stuff is your second favourite saying, whats your first ?
cheers
