Do you think this part is a worthwhile upgrade then? How likely is it to have the hinge pins come out with the stock piece during the course of a race? You said your diff cases are still good, so do you see this upgrade transferring other weaknesses anywhere else? I finally took pics of the CL-1 in kit form. It's also built now so I'll take some pics once the body is painted and figure out how to post them here. Sure is nice to see GS posts, I still race my old Storms and can't wait to race the new CL-1. Talk later. Brett, Upside Down Racing Team.
