I ordered a M/C bar for my 1970 coupe last week and received it today. Received no instructions, no mounting nuts or bolts, nothing but the bar itself. I monkeyed around with it to see if I could figure it out; it looks like the top two holes of each bracket need to be drilled and the bottom two are supposed to line up with existing bolts on the inner fender aprons. Problem is, a couple of the holes for the existing bolts don't line up either. Can someone who's done this installation please give me some guidance?
