Problem solved crooked hex screw that was protruding from the mechbox. It took me 10 mins to gently tap out the gearbox with a flat-head and a wrench.
Side note the selector plate and disk is fine, I'm gentle with the ladies
Turns on the screw is bent and the head is pretty stripped (Someone wasn't being gentle) waiting for the customers next choice, pay me to go to Brafasco, Jerry rig a screw that fits or give it back to him as is with the screw removed.
