Swing hitch

I've a 2619, and I'm interested on having the front hitch converted to a swing hitch, the spare mounted to the front, and having the rear "bumper" shortened.

The unit fits in our garage, but it would be convenient to have a bit more space.

My questions are:

Any suggestions on someone reliable in Southern California?

If I shorten the rear, and the factory bike rack still be installed, and work properly?

Has anyone done this recently, and do they have an idea of the cost?

Thanks!

Michael
