I can't do that - too old
I am too old to get under there and tackle that project.
I did make a new tube for the manual operation of the slide - drilled the holes and installed the pin in the outer end. It looks like it may have broken a shear pin on the inner end. The holes are wallowed out some and bent outward from center of the tube at the holes. A broken shear pin would be an easy fix, but my dealer is going to tackle that because of the under belly issue.
The tube that I used to make the new one is the same OD and looks to be a little smaller on the ID.
It took a lot of care to drill the holes in that small strong tubing - even with a drill press, because those small drill bits want to bend to one side or the other of the top of the tube - in retrospect, I could filed a small flat spot of v-notch to start the holes.
