Derek Wadsworth isn't too far from you and is very familiar with the Dolomite:
Hi Terry, Yes I've used Derek 4 times before and he does a good job as every body else says.
One that might also be nearer to you (possibly?) is Beech Hill Garage.
They did a jolly good job on Wife's MGBGT some years back.
They do have a long waiting list and are quite expensive though, but I did ask them if they did other cars other than MGs and Will there said his bodywork guy was happy to look at any B.L. car.
