Why does your lever, the same one I specified before... still look bent? Using you last pic, that uppermost lever "ring" that the main spring sits on should be flat, right up to where it bends up to hold the clip and rod. Even the arm should not be sitting "angled", it should be parallel with the rest of the mechanism. Take a good look at my second pic with the L bracket removed but compare the lever I circled before. Yours is still bent. Secure it in a vice and gently hit it with a punch, right in the folding corner of that uppermost lever... until it sits flat again.
edit add for further illustration...
* center, uppermost lever is bent, just like yours. It's literally sticking up crooked in the top center of this pic.
* center, uppermost lever is restored to oem position... (note: the L lever has yet to be removed in either of these pics)
The rod that goes from the mechanism to the handle usually gets "stretched" lengthwise, so when you put it all back in place, you'll have to bend it again, to pull it in tighter, until the handle sits flush in the tailgate. Any Bronco with a handle that doesn't sit flush with the gate has had that rod stretched, at least and probably the same bend in that mechanism. I've never bought one and rarely seen one owned by an "average" whoever, that did not have this problem.
All of the damage you're dealing with happened because the rod that catches the window at the bottom, when it's completely rolled down... pulls on the L bracket and moves it out of the way from blocking the natural opening of the mechanism, when pulling on the handle. You can see where it sits, blocking the mechanism from moving freely... if you look at the L bracket on the other side from the rod seat. Unfortunately, if you pull on it hard enough, the weak metal will eventually give, allowing you to open the gate with the window not fully seated in the down position, over-riding the safety feature and damaging the mechanism. That's what has happened over years/decades.
Removing the L bracket and the rod, as I showed before... eliminates the safety feature but resolves this ongoing problem. If you choose to go that route... you need to be mindful that dropping the tailgate with the window still raised enough to contact the edge of the gate, can easily shatter the glass and potentially cause inury, or at least a considerable mess and major hassle, replacing said glass/defroster/etc. Handle according to your ability, confidence and that of others you may let use your rig.
That said... removing the L bracket is easy. I simply took a grinder to the rear of the rivet at the center of the L bracket, on the back side.
Once you've done that... no need to install the safety catch rod (or a place to put it, for that matter) and you might be able to re-use that same rod keeper, plastic clip... if it's in better shape than one you're keeping in service. If not... I've seen them available somewhere but have no idea to link you.
Switch goes back, if you want things to work... yea.
