Just coming across this ancient thread now. Having just replaced such a toggle bolt plug that had started to leak, and struggled a little with removal myself, I thought I'd share my easy experience for others that might come across this thread.
The toggle hinges at the end of the bolt. Unscrew to the stop, then you should be able to stick something (screwdriver, awl, or similar) into the hole and tilt the toggle to parallel with the bolt instead of perpendicular to it, then just pull it out.
Mine appeared to be this one:

The bolt hole was a mess; front was totaled, rear still appeared to be OK. I re-tapped it with the E-Z Coil M14-1.5 (1.5D/21mm) kit, and I'm hoping I won't have to retap to M16, because there isn't enough clearance to get a drill in there with the frame in the way, and dropping the pan requires removing the exhaust... blah blah blah. Luckily on these vehicles the original plug is only 9mm long but the bolt hole is something like 20mm, so only half of the threads can be stripped out by careless people. You can get a longer bolt to grab the threads in the rear, and I have one on order for the next oil change just to set my mind at ease, though I was able to torque the somewhat-longer-than-9mm Dorman plug I installed to spec and it seems solid.
Incidentally, it's just a flange bolt, which you can get in all sizes from e.g. BelMetric. Might have to cut it down to length. You just have to be sure the flange diameter will fit if the port is recessed.
A nod to the E-Z Lok folks: I got a kit with the wrong size parts in it from the retailer, and when I reached out to E-Z Lok because it was then out of stock at the retailer and I had to do the repair that week, they immediately shipped me a replacement kit with the right parts via Next Day Air. Quality product and amazing customer service equals customer for life.
