Re:
I successfully completed, installed, and set up the M900 rear franken-mech (that I custom hand-fabricated an SGS cage for - pretty much using actual hand tools only) onto my retro-mod Romax, and it works and looks picture-perfect!
Too bad I don't have the tekno-wizard skils to be able to up-load photos onto the forum (such a Ludd!).
I ended up adapting an M951 outer cage-plate and pivot bolt unit, behind which went a pair of lovely red-anno jockey wheels supplied by RacerX, which in turn are held into place by a gorgeous aluminum back-plate that I hand fabricated out of a sheet of scrap aluminum ... and it turned out as almost an art-piece!
And ... it all works (indexes perfectly, with my XT M-095 STI shifter set)!! All that work late into so many nights, and it came together just as I had hoped it might.
Other than re-wiring a pair of Cree riding lights (for which I also hand-fabricated a set of mounting brackets and plates) ... she's pretty well done (it only took one full year)
I'll now have to figure out a way of posting a build thread/story, with photos ... :facepalm:
