Here is a quick tip. The No. 2 soft top bows have fabric straps called stay straps that need to be attached to the No. 3 and No. 4 soft top bows using five pan-head screws (per side). To predrill the holes for these screws, we ran a hex-head No. 8 self-tapping screw into each of the holes in the two soft top bows with a wrench. This will help preserve your sanity and keep you from stripping the Philips crosses out of the supplied pan-head screws.
