For rods with .791" diameter wristpins. Used to check connecting rod straightness with bottom end of engine assembled. Centerless ground from premium US-made 4130 through-hard steel. 5" long, 1/2" longer than most similar products, for easier use in both stock and big bore applications. How to use: Slide tool in wrist pin bushing. Slowly rotate flywheel until tool contacts the crankcase gasket surface. Slide 2 small strips of paper under the tool and make sure they each pull out with an even amount of tension. If corrections are needed, adjust (bend) rod until paper pulls out with even tension on both sides.
