Review on Tenhulzen Plates Degrees Conversion Included by Stanley Molden

They will work but make sure you have a flat surface and the edge of the rim is not dented where the posts meet. I was skeptical of these plates so I checked the string alignment and the readings were accurate. If you have a rocky surface (in the picture I have rocky asphalt for example) this can lead to measurement errors. Both plates must be in full contact with the ground so that they cannot rotate or otherwise move. On asphalt it's more difficult than it seems, you may have to move the car. Your video shows rubber feet on both sides and that might help. I don't know if they came with mine. If your rim has dents where the struts meet (my metal rims have dents where the balance weights used to be) you will need to reposition the car until it goes away. All posts must make contact with the true portion of the rim edge that is not bent. Double check your measurements from one panel to the next to make sure they are still secured and in the correct position. Once I held out a tape measure, but the metal end of the rivet caught on the panel. You want to be sure that everything is correct when measuring. After receiving these panels, I was concerned because there was a small gap when I held them back to back. Turns out there's a gap on both sides, which the seller says is part of the manufacturing process. I have confirmed it. I also lined up the racks and placed them back to back, holding them in the middle (slightly so as not to warp) and also got the same measurements on both sides. See diagram. Nylon nuts suck and cross threads easily. They give you something more.
