Well I purchased some dubro vibration reduction mounts and there huge and require drilling new holes into my hanger 9 p-47 thunderbolt. so I just like to know if the aluminum mounts really help reduce air frame fatigue, or is it more of a gimmick? Oh and it’s so bulky I haft to move my hi speed needle, not to mention that I’m sure I’ll never get close to the precision placement the current laser drilled holes.
