The first set of pegs were returned. The second set looked as nice as the first pair. I had to start each bolt a little by hand and then drive it home with an impact wrench. The threads have too much powder coating on the threads. It acts like red, dried up loctite.

Also, one arm moves downward further than the other. They are both adjusted level to the ground and I also took measurements. One travels downward almost one full inch further than the other. It's weird and I cannot see how I can adjust these.

Let me know if anyone has had this issue and knows how to resolve it.
