Hi, I bought a set of used flat top pistons (Gen4) for my 5.3 (Gen3) and also a set of Gen 4 connecting rods. Pistons came with wrist pin that seems to be the wrong diameter (.945). Also, wrist pin do not fit my Gen 4 connecting rods. Does anyone know the diameter of Gen 4 wrist pin? Should I buy new one in .927 diameter? Thanks!
