How does one go about acquiring a connecting rod for 1958 261 ...casting number 3836964. I have 6 rods, but one is different...and about 27 grams lighter than the other 5. It has a different casting number (3836456) and looks like the metal is a different color. I noticed all this when I was weighing them to check for balancing. I'd rather have 6 matching rods. Would it be ok to just lighten the other 5 rods?
