Holy Smokes!!! finally a reply!!!
Yes I do mean to join the edges to form an L. It'd be dampened somewhat by the stock bolts with rubber washers.I don't expect load as in weight bearing,but I do expect vibration which I think would be tolerable by the joint(for how long is another question). I picked up some clear drying 2 part epoxy from my local hardware store just last night and am going to make an attempt whith that.Worst case scenario,I loose my plate and have to go to DMV for a new one
