replacing rear spring shackles

I have a 98 and the rear spring shackles are going bad, I know they are usually a easy fix, my question is the bolts are going to be rusted, is there a good way to get them out...I'm a little skidish about using a torch around the fuel tank filler pipe. Anyone know a better way to remove them

How about a reciprocating saw/sawzall?

A good quality socket on a breaker bar with a 3 foot pipe extension. Just rock it back and forth real hard until the head breaks off and drive the bolt out with a sledge hammer and punch. This works great when replacing shocks too.

Thanx for the replys guys...I haven't had a chance 2 work on it yet...weather is now just startin 2 get warm enough 2 work on it..will give both suggestions a try thanx again..will report back when I get the bolts out
