welder woes

Need to get a new tip for the welder to use the flux core. It's a bigger diameter. I'll get a pic of it soon. My wife has the camera on a trip at the moment.

I did find an interesting site today: http://www.ecodeparts.com/ They sell euro diesel engines. they have a 1.4 tdi that gets 60+ mpg. If I could put that in this project with 500-1000 lbs of weight reduction over the car that gets the 60mpg I could get 75mpg+ and still be quick.
