Yep, as above, I had to cut about a 1/4" off the end of the back bolt on both sides of the frame to keep them from rubbing the uprights. One suggestion if you do cut the bolts ... run the nut on as far as it will go before you cut the bolt, chamfer the end of the bolt a little after the cut, then run the nut off. The nut will help to realign the threads.
