I got them from Maverick Connection. His price was the same as autokrafers but the shipping was much less.
Mavaholic is right. Be very careful when you weld. Too much heat in one area can ruin all the good work you have to this point. My best advice is do not try to run an actual weld "bead". I choose to use more of a tack weld aproach and skip around on the panel to cut down on concentrated heat in any one area. Once you get all of your tacks connected it will be solid like a bead, but with MUCH better results. Also it will not be as high as a bead which makes the grinding and the bodywork easier. Remember if you really get after a weld with a grinder, that can also cause enough heat to warp a panel. Just go slow. The extra time you take is well worth it.
Thanks for the advice. My next problem is my welder does not reach the car. I need to make a 220volt ext. cord
