While you’re at it you might want to consider a Tally-Lok Rudder Gust as an additional to your gust/control lock. The gust/control lock does not stop the rudder from getting slammed around. See them at AirCraft Spruce. I have an M model but will try and take a picture of the gust lock tonight.
Yep! The Rudder gust lock is also on my list, but I already know how and where to get one of those, and they don't differ based on model.
Thanks for posting the photo of your M model gust luck, but unfortunately it's different than my '72 L model. Your M-model has a gust lock that is vertical, whereas on mine it's horizontal. That's why I'm specfically looking for other L-model gust locks. It's crazy how there's different variations.
