Fit and drilled the left and right flap bearing blocks. Started by removing the panels that covered their location. Measured the hole location for the botton hole on the left bearing block and drilled that hole on the drill press. Attached the block with the lower bolt and then marked the location for the upper hole. Removed the block and drilled the upper hole on the drill press. Repeated the process for the right hand block.
Measured & drilled 1 hole, attached the block and marked the 2nd hole location
