Chris, try this.
Before you pull the coils out heat up your plug for 30 sec to a minute. This will temper the wire and make it less likely to break. Pull only two coils out and don't try to get the full 1/8 inch. Just enough that the two coils are exposed above the end of the plug.

In a pinch you can use any plug. I've even cut the idle bar off a plug and used it. I flew my Eagle all last season on a Fox Standard plug that I used in a pinch and it just kept right on going.
Hope this helps.
