I trimmed the tabs and installed the nutplates in each LGIF, then temporarily installed to check fit and alignment. They worked out very well. I've left just enough room for either epoxy/Aerosil filler or 1/16" neoprene sticky-back foam to take up the gap (with UHMW tape wrapped around the gear leg itself for abrasion resistance). A few more checks to do first and then I can drill for nutplates and screws with tinnerman washers to hold these in place too.
