I am planning to make a set of door hangers this spring. If I can find a donor Jeep at the salvage yard (they're few and far between in this part of the state), I'm going to take the male door hinge posts off, and either bolt them to a 2x4 or directly to the wall studs in the garage to hang my doors when they're off for summer.
If anyone has any they would like to sell or donate, let me know.
