Need help finding ARCA-Picatinny Clamp for LeoFoto Tac Plate, want to mount spotting scope. Looked at Area 419 but nut/wheel to tighten clamp below base unless spacers used.
Tried RRS B2-LLR II Long Lever Release Clamp, having correct spacing of the 1/4"-20 outer holes (45mm). But the lever was too log and would not open to release the ARCA plate. Still searching Internet. Hole spacings on Tac Plate 23, 34, 44, and 55mm.
