These work much better on the outside of the cover instead of the inside. I've always had problems with the cover not completely closing when you place the tabs on the inside. For the SL-D2 type tables you line up the base even with the dust-cover (see photo). For the Q200 type tables with the shorter cover you will want to line up the actual small tab with the bottom of the cover. I use #8 machine screws (included) which work perfectly. If you want to drill a slightly larger hole in your dust-cover this will give you some wiggle room in case you're slightly off with your drilling. To grind off your broken tab you want to use a for Dremel (or equivalent) and take your time. Make sure to wear safety goggles and remove as much as the old tab as possible so the back of the cover is nice and flush. Once that is accomplished you want to line up the new tab in the proper position on the cover. I use painters tape which doesn't leave residue and is plenty strong enough. Check to make sure the new tab is in the proper position by placing the cover with the tab (held by tape) in your tables hinge. This is easier if you're replacing just one tab but if you need both just take your time, you'll be able to see the area where the old tab was by the for Dremel marks. Once your all lined up it's time to drill out the holes in your dust-cover. These Technic covers are strong and I have never cracked one during the drilling process. This is important, Leave the tabs ON the cover (still secured by the painters tape). You'll be able to feel where the holes are in the tabs and drill accordingly. I have used this method many times and it works great!
