Restoration begins with media blasting of the various housings to restore a like-new finish that will stand up to the toughest NCRS and Bloomington Gold judging standards. The technicians at Corvette Specialties are always careful to preserve original part numbers and other stampings that appear on the backs of the gauges.

Odometers and tachometer rev counters, where applicable, are completely disassembled, serviced/repaired as necessary, lubricated, and reassembled. Brian and his team are able to replace counters that are no longer serviceable, and he cautions that others in the business who do not have access to correct parts sometimes use counters from passenger cars of different years and even from other GM car lines. The numerals on these "replacement" counters may look significantly different than the original Corvette units and cost points during show judging.
