/\ HAHAHAHA... i soo gotta try that with my car sometime.

Just watch yourself with a welded diff. I've heard horror stories of people blowing up their diffs while driving and throwing shrapnel into the car. If you're gonna do it, make sure you have someone who is very good at welding; clean up the gears very well and heat them with a torch before you weld them.

so thanks for answering my question again guys.. is the forum really becoming this useless?
