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.

Ben S. I made the bucking bar. The rivet gun is a commercial one. It is not as controlled as riveting with a hydraulic squeezer, but less tooling and inexpensive. There is a little art in making nice looking rivet heads, but the good news is - you can fail, drill the rivet out and have another go!I have another frame to do later this fall. I will take a deep dive into riveting when we do.
