40k bed brackets for adjusting levels

I have adjusted the location of the brackets to the front and back the bar over the motor in front keeps the front backets in place. I can't weld so I used the piece from my previous bed and screwed them to the bed so the bed would for sure move with the nuts. Also I left the knobs off so I could use my screw driver to quickly lower and raise the bed and for finer adjustment I used a hex screwdriver. Back pieces go under the bar and snaps over the top. When I attached the bed I squared it at the bottom of the bed so see where the bolts should go in to keep it square.

There is a right and left front piece since one side has a motor.
