Quick Repair!

Coming from a guy that put 30,000 miles on a nylon ratcheting tie-down to hold my gas tank in, I'd say that might not hold up. I'd have put the bigger Vise-grips farther out where the smaller on is. As someone else mentioned, C-clamps would be good, too. Also, need to introduce some wood to the repair - maybe 2x4 or plywood. Last, as others have said, there's a waste of extremely valuable duct tape there. One wrap around the handles would suffice. Everything else is window dressing.

I can also tell you from experience that no amount of duct tape and vise-grips will hold together a broken tie-rod end on a Cadillac for any sort of distance.
