>But it turns out this thing uses flatheads in evil places. I've tried wrenching on it with the widest driver I have using a wrench as a cheater bar. Think I'm gonna have to buy a impact driver for this. Any thoughts on how to get this apart?
That flathead is the adjustment for your detent tightening it up makes the detent harder and loosening it off will make it pop off easier. They can get quite crudded up after a while because it seems like moisture and other crud always finds its way in there.
As the other anon said try and break it loose with an impact driver. The screwdriver type that you hit with a hammer. Get a good fitting bit, hold it in there tight with a firm counterclockwise grip on the handle, and then hit it with your purse like you mean it so you don't fucking strip the head any more... A bit of WD-40 or other penetrating oil and a bit of heat couldn't hurt either.
