This is a new old stock Ammco factory 902572 gauge adapter GM "W" body for use on a 1750 Brake Resetting gauge, specifically for rear drum brakes on 88-93 Regal, Cutlass Supreme, Grand Prix, and Lumina sedan. It's been sitting on a shelf in my garage for 28 years. The adapters are stamped "AMMCO 2572" and has its original packaging and instruction sheet. This would have been part of the 1750 set, but I'm fairly certain this is the only individual adapter set available anywhere. Please check out the other Ammco and Coats service parts and accessories I have listed.
