The "BTF Curved Coilover Tab for 1 3/4" Tube" is laser cut from 1/4" high-strength steel plate.  The tab measures 1 1/4" from the edge of the tube to the center of the bolt hole.  The bolt hole is 1/2".  This tab is curved on the bottom side to provide clearance for the shock body when the tab must be rotated up for more height.
