Walt, I am unaware of anyone making tubular front A-arms. If yours are damaged or need replacing I do have a large stash of front upper and front lower control arms and you can get new bushings and ball joints from places like Kanter (www.kanter.com), etc.
I was just seeing if maybe someone had used something and where they may have gotten them. I did find ones for air bag system. but thats not my style nor do I want to spend that kind of money. I'll go through the stock stuff and leave it at that.
