95 P38 Caliper Seals / Repair Kits

Does anyone know if caliper repair kis are still available in this throw away world? I recently changed pads and the piston dust cover was well past its sell by date, asked my local factor but only got blank looks so I did not persue the matter as it was obvious too much for their collective brain cell. Any help with availability or part No would be greatfully appreciated.

Thanks for that quick reply it was just what I needed.
