In some cases yes. I had the completely remanufacture the landing gear for a project I’m working on right now. Original parts from 1941 aren’t available and the gear we had was beyond saving. Good thing is, it’s all chromoly tubing and relatively simple. I also did a repair on the bottom of the rudder. Someone had done a brutal hack farmer’s shed type repair and I cut the bottom off and rebuilt it properly.
