A few other things that likely will never go on my SD rack given the current setup.
1 pair of Coleman Racing accessory brackets (pn 900-400; http://www.jegs.com/i/Coleman-Racing...0-400/10002/-1
) Mounts on 1 1/4" tube (can be shimmed for 1" easily). Uses 1/4" hardware for mounting of whatever. Brand new, removed from packaging for some mockups previously but never employed in anger.
2 pair of PIAA ~1" L bracket bar clamps. (http://www.amazon.com/dp/B001AWJ9U4
) Unused, these might be the 1 1/8" setup (also easy to shim like the Coleman setup). Comes with the L bracket to mount lights or other accessories at various angles.
$20 per pair shipped, $40 for all four shipped
