Anchor bracket design approach.

Anchor Bracket do reverse engineering, you can do it yourself

From the sketch you can get all dimensions required to model part. What you need to decide is if you want to copy as is, a cast anchor bracket, or is it better to re-design to make version profile cut from plate and welded together. This is a decision based on quantity to make, tools available in workshop / factory and analysis of costs involved. The CAD system does not matter, this approach applies to Solid Works, Inventor, any other CAD package, or even a quick hand drawn sketch

The attached images are of a possible version laser cut from 6mm plate and pressed to shape. If the bracket needed to be stronger you may need to weld in a rib between the flanges, but if this as is is strong enough this would be a cheap way to make this part, a few off to hundreds or even thousands off.
