i have a 97 civic LX.

i have a problem with my rear shocks.
when i tried to take the one bolt off the shock, that connects it to the lower control arm, the head of the bolt broke off...
i have tried using easy-outs, but the bolt just wont budge..
is there an easier way to do this? i was thinking about drilling it out the rest of the way, but then i was thinking..
wouldn't the pressure of the spring break the drill bit??
how would i go about doing this?? any suggestions?

anything helps..
