Show Car Door Props for under $30

It's Saturday, and the car show is Sunday, and the forecast is for a windy day. You have a classic Beetle and the doors free swing from all the way open to close. 4' Flat steel bar stock $12. Hardware $2. Spray Paint. $10 and about an hour of tinkering. Had my wife cut some graphics on the Silhouette machine and BOOM. Car show door props. I will likely add some rubber around the side that attaches to the door frame, and shorten the bolt so it doesn't tilt as much, but overall very happy with the result.
