Oooh... speaking of the men you know Neil... are you familiar with the armadillo butt hook? I would like one of your twirly knobs, well, 2 actually, to go through the rear of it... they provide the clamping force to keep it on it's rail... there's one in the middle that has a special recessed nutt, but i've taken that off... i'm looking for the ones above below.
Can you help or do you need a photo and some measurements?
All black would be nice
or just blasted ally even better.
