    Here's what I have. All three joints have straps welded around.

    Guy I really like your welded straps. As a mechanical engineer, that fix looks the best to me.

    Chuck, mine came with the springs. We will have to ask the forum if they are required, as I have no idea. Great question!

    Some master cylinder designs have the external springs and some have them internally installed.

    Sorry for the stupid question, but i am about to reinforce my pedal tube assembly (finally, after 10 years flying with the original model IV design, it is time to do it...).
    I am strugling to remove the plastic bushings at the end of the torque tubes. Are they supposed to be glued inside the tube? If possible I will try to reuse them.
    Thanks!

    OK, I finally got them out. I actually felt a lot more confortable pulling hard on them knowing they were not supposed to be glued! Thank!
    Now the real work starts, making and welding the gussets.
