More progress pictures.
You can see the bellcrank in the preceding entry covered in rust and mounted to a section of frame with rivets.
These pictures show after removing the rivets and cleaning up on a bench grinder mounted wire wheel, and then assembled and ready to mount, then after drilling the mounting bracket holes slightly- and modifying the bolts I planned to use to cut new threads into the Suburban frame, finally mounted- after a little over 2 hours of making things all come together to work out correctly.
