I ended up with the Mellings MPR-31 rods. I was confused at first since summit listed them at 10.444" long. When I went on Patricks website he listed rods at 10 9/16"(10.5642"), which ended up being the MPR-31 rods. They measure up nearly identical to my original 228 ones. The rod shaft is thicker. The original being 1/4" and the MPR-31 is 5/16".
