I have a ton of the old style Bessey K-Body clamps in sizes 12" - 60". Most are drilled for the black plastic rail end clip. I really like how the clips hold the clamp level on the bench. The oldest ones were not and years ago ground the bars and drilled them to take clips. Jump forward to today and the old style clips are no longer available. Does anyone know if the new Revo end clips will work on the old non-Revo clamps? If the new clips won't work, I may design a replacement and 3D print some.
