Ahhhh... THAT bar. KK.
Nope, don't have any spares.
There is a bit of a market for those it seems though... seems like it's a pretty common failure point.
I'm a cheap bastard though... so I'd probably temporarily glue the thing into place, drill a tiny hole through both pieces, put a little metal rod through both pieces with epoxy, then epoxy the whole thing, and clean up/trim the excess epoxy and hope it holds long enough for someone to repro a few.
Side note... to drill the hole you'd probably have to drill out the poprivets, then redo them when you're done. ... I had to redo a rivet on mine and it wasn't anywhere NEAR as fun as it sounds (read as: not fun at all).
EDIT: If anyone gets all motivate for this machine... a stencil to repaint the scoreboard would be pretty sweet too... just saying. ... and a vinyl underlay type deal for the bezel would be nice as well...
