So, my 91 TII instrument surround is breaking apart inside and as a result it isn't holding the turn signal, headlight, wiper switches in place.

How have you all fixed that ? I think it is a common issue?

Thanks!

Very common, as most of the interior parts are cheap plastic and have been taken apart multiple times at this point in the car's life for repairs or modifications.

You can try to hunt for one in better condition with more of the mounting holes intact. But you are on a 1 in 100 search to find nice parts like that.

You can gently drill deeper into the screw holes and then use longer screws to go into those holes, and hope this holds up for a few years.

IF you want to do it "the right way" to have the best chance at success, you'll have to take more time and effort. You'll need to find some way to epoxy around the screw holes and rebuild/reinforce them. IF you could find a tube or sleeve that is maybe 1/8 - 1/4" larger in diameter than the screw hole casting you're trying to repair, you could slide it over the casting, then pour epoxy inside and let it set. Then drill a new screw hole to the appropriate pilot size and you're good to go.

The same goes for the housing attachment points in the dash. The bottom two are always broken off so if you want to stop the housing from flopping around as you drive and rattling, you'll have to rebuild those tabs and holes using epoxy or fiberglass. To do that you have to build some kind of jig to hold the shape while the epoxy or fiberglass sets. Then you remove your jig, and use a dremel or similar tool to shape the tab.
