Looking For 3D CAD file For JD Front Quick Hitch

[wirlybird]

Searching for a CAD file for something like these. Going to design a unit for the front loader (300E) and it would be nice to have the CAD file for these plates.
If anyone has any ideas I'd appreciate it. So far no luck.

Make sure you use the right grade of steel, else the work will fail.
4130 or A572 Alloy Steel. Both are strong and are weldable. Plus the correct thickness is critical. This way you can mimic the strength as a JD loader overall.
