Made up the wire ball guides, these were pretty easy to bend by hand in the vice - although the radius is a little larger than factory. The NBA FB had heaps of these, so just cut and bent them.



One of the challenges was the shafts for the drawbridge assembly are not available. So i bought some 4mm stainless rod, and made up a poor man's lathe with a drill press and dremel to cut the slots for the e-clips



I was pretty happy with the outcome, almost looks factory!!



All this stuff is tricky as the manual is next to useless with no measurements and diagrams very messy. So most of this was made from pictures on the net and from other people.  Once the two shafts were made, it was a matter of installing the gears, then cutting some old post spacers up to align the last gear cluster



Hooked up the motor, and it all works perfectly!! I made a short clip showing the process
