Hold the reference steady
Start with a readable part number where available, the implement identity and a dimensioned sketch. Record hole diameter, hole-center distance, thickness and the seating face. Photographs help show the shape but do not replace a drawing when dimensions decide compatibility. If the existing part is worn, label measurements that may no longer represent the original profile.
Specify quantity in pieces or sets and explain whether bolts, nuts and any retaining hardware are included. Keep material and treatment requirements on the same revision sent to each supplier.
