Sorry Cane C, you must have misunderstood my statements, or, I did not offer up enough detail about what I was trying to convey to you. What I did was to buy another set of covers from a captain who had them up for auction on Ebay. My statement was this, I purchased another set of side covers, which were "Triumph" fabricated parts, and they fit right on. I was pretty much refering to the fact that "after market" parts must not go through quality control to assure the dimensions between the mounting holes are correct, or at least close enough to fit.
Sorry to have done a poor job of explaining my experience Cane C.
Good luck with your covers.
