Christian A. The Willys versions are replaceable from the top. Not sure where you are (Switzerland?)....Peter Debella has the correct ones in the US. I have replaced them with the cover off-little finicky but possible. I believe the Willys ones have to be flared out...I made a crude spreader and used a bolt....probably can find a picture somewhere. 

I have fixed a GPW too...but don't remember how the GPW's are attached and whether they are the same style. think they are a little different and much easier to install...like flat tabs bent over maybe? They might be spot welded too. which is a little harder, but you drill a hole where the spot weld should be and plug weld them from inside the tub. If you have a TIG welder...it is really easy. 

If you have your cover off, post a picture and I can be more helpful.

Steve G You are absolutely correct - the Weasel also has the .50! My bad!!

Jim B. We had a blast seeing you guys. Love that gorgeous Weasel. Thanks a bunch for letting me fly that drone!

That is really nice. Thank you for sharing Dave!

Greetings Lance. We are out of storage....and are talking to our technology providers to get this resolved. We may end up with an app too...which is why this taking a few days to sort out.

The parking brake how to is new...will have this resolved and get the video up before the end of next week. Apologies for the delay!
