new sawsall blades

torch is the best blade I have used but I won't use them on converters I know have a type of exhaust pipe going into the converter as certain one's will chew through blades (lumina's, grand prix's etc) so I stick with cheaper one's for those pipes, and when it comes to those pita dodge vans I start by cutting the carpet, drive a stepper bit through the floor and cut a big hole in the floor, once you do a few it doesn't take long at all
