I then moved on to the replacement of the T-Top header panel. This was the only rust on the body. T-tops are notorious for rotting out. The process was to drill out every factory spot weld and size up your cut on the A pillar from the new header panel. The replacement panel I purchased from Mikes Montes website. It fit perfectly. The factory fused the A pillar to the header panel with lead. I chose all metal filler when I went to bond it back. Not sure if that is idea, but I've been using All metal for 15 years and its never let me down. I drilled as many plug weld holes in the header panel as the factory used. Tig weld would be better but a mig welder works just fine. make sure to use a welding blanket over anything you don't want burnt from slag. Use a weld through primer before you weld. It will help prevent future rust. A rust preventative should be used after the welding. I use one from Permatex.
