Can anyone ID these traction bars?

Here's a picture of the mounting pads. I started stripping the one bar. Its interesting that two of the four mounting holes are welded shut, mainly because they interfere with the tubing on the underside. Also the bars are at an angle and not parallel to the mounting pad! I have seen this on some Lakewood style traction bars before so that might help explain what application they might fit?

Homemade I would bet by a car guy who was a welder. . Never seen these in any catalog nor on any car.
