Unfortunately there are problems with all of these suggestions, but keep them coming, please!.
1. I think the heated up socket would cause damage to the plastic around it, not willing to risk that.
2. The bench grinder suggestion sounds nice, but unfortunately I don't have any tools like that.
3. I looked at some pics of ignition wrenches, but they didn't seem much different from a normal wrench, and there just isn't enough leverage of the exposed part to grip it.
4. Not enough room to get a good enough grip to actually turn the damn thing, the bolt is in super tight, so that doesn't help things.
5. No way to use a dremel in that tight area without damaging the plastic.
Thanks guys! I'm really stuck here on what to do. I might just have to live with the yellow acceptors, but that's really annoying since I already bought the blue ones, and every other Stern I have doesn't have this damn issue!
