Yes, I was looking at a Harbor Freight welder on sale for $95! 125 amp, welds up to 3/16 inch steel. It's a flux core wire feed. Would this get the job done? Haven't welded for 30 or more years. But welding is like riding a bicycle, right? You never forget how. LOL. Also found out my Dart Custom is a 111 inch wheelbase. I was shocked! All this time I thought it was a 108, but I measured it. Must have grown longer while sitting in my garage! Ha! Seems to be some misinformation from the parts warehouses as to what years and models are 108 or 111. Any clues on the various A body models wheelbase length?
