The PO on this project bolted a roll bar right to the wheelwell by using some steel plates and drilling two 7/16 holes for the attaching bolts.The roll bar was gone, but the holes are still there. I want to plug the holeswith a smooth sealing finish on the wheel well. One thought was to cut someplugs the size of the hole and butt weld those in place then seal them withsome body glaze and paint. I am a loss about making the plugs. I could cut themwith snips, but they are small. Any suggestions out there?
