The OP wants to stroke his engine and use the OE connecting rods. It’s cost ineffective to do that. By the time he buys a decent bolt, gets new bushings (the bushings should almost always be replaced) and rebuilds the rods he could have a set of aftermarket rods that have 7/16 cap screws rather than 3/8 bolts and nuts, plus a better grade of steel and a better design. It makes no sense to use OE rods any more.
