I cannot find a drawing for this part and need the hole size and dimensions -- RAM-D-202U-CRO1
The 4-hole spacing for the RAM-D-202U-CRO1 is 1" x 1.75" with 2.5" distance between the wider 2-hole pattern. RAM recommends using M5x14 screws for the 4-hole pattern and either M6x14 or M6x25 screws for the 2-hole pattern.
