The ones I have just leave room for 2 sheets of paper between the left one and the pannier. The fitment instructions specifically say you gotta lean on them before you tighten the bolts, or they'll touch the pannier. The RH side has more clearance. Mine are the ones removed from Goldwings that were converted to trikes, and a a bit beefier than those. And they're chrome, which is a nice touch.
