I thought your car was narrower than the available hoops. Is there anyone in your vacinity with a tube bender? If not, I can have one bent for you from 1.750" x 0.134" and shipped. The rest of it, you could fabricate yourself. It's all straight tubing.

Dave Severson is closer to you than I am. PM him and ask if he can do it for you. If not, I can.
