I am in the middle of installing new SW-Motech crash bars on my '06 Wee. I can not loosen the engine mount bolt, do I need pneumatic tools for this? Is there something I need to do prior to loosening this bolt? Is the engine going to come crashing down once I pull the bolt out? I have some Tim "the toolman" Taylor tendencies when I try to do something myself. Could someone please give me some advice. Thanks a bunch.
