I use a lot of round rod to build things…here I’ve bent it to add rigidity to the inner panel, the area in front of and behind it will be filled in…and… on the driver’s side, as you can see below, is already welded in and done. These took several days each to build…and get them to look correct…I hate something that looks out of place…like it hadn’t ever been there and simply tossed on cuz it had to be in that certain spot…wrong way of building things, IMHO
