I sold a parts car the other day, and the guy who picked it up had a bumper mount tow bar. I'd never seen anything like this before. It hooks around the top edge of the bumper, and has 2 small chains with hooks that clamp to the bottom edge. Then you tighten 2 nuts and it pulls the chains snug.
When I asked where he got it, he told me he got it from his brother who had bought it at an auction a few years back.
Obviously they would be no good on any car or truck without a solid metal front bumper, but seems like a good alternative to renting a tow dolly to get a project car home a short distance.
Anyone ever seen one of these, or know where I can buy one?
