PISTON BASE ALLOY HOLDER

Alloy plate that slips under the piston to hold things steady when rebuilding the top end of the engine, the grove fits around the Connecting Road and flat onto the Crankcases then the bottom of the piston drops down onto it to keep the piston 100% up right as you lower the cylinder onto the rings. This makes fitting the Piston into the cylinder much easier on 2 and 4 stoke engines.
