Ok, so I am learning how to tell the difference in connecting rods but I have one that stumped me. For our trophies, we use the standard 1300-1600 rod, the part number is something like 311-105-411B. They have studs on the caps and nuts to secure the two halves. The 40hp rods, which have the part number 113-105-411A, have bolts the to through on the rod side and thread into the cap. But I have found some 311-105-411A rods in a bucket that was donated. They look identical to the 311-105-411B rods but they have bolts like the 40hp. I am at a loss as to what these would fit and google has t resulted in much either.
Anyone know?!?! Are they valuable before I doom them to life on a trophy?
