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.
