Verburg is right, I remember going through this drill. Of course I had production rods which do not have the last "weight class" digits stamped on them! On to the scale. Since I had new P& C's I weighed all the reciprocating masses and made the best combinations of pistons (complete with rings, wrist pins, circle clips), connecting rods, bearings and rod bolts. I also remember that the 2.4 rod's were NLA new so I obtained a used one from Parts Heaven and had it refurbished by Ted Robinson.
