The video was fabulous... used wood to prop UP the door (with shims to hold it tight)... couple of 5/16" bolts. One thing... when you pull the lower hinge part off... leave the lower black plastic piece in place. It looks a LOT like the door cam, but it is not... its what the door cam rides on.
While I was ordering that part, the meat pan cover had cracked and lost one wheel... so we just fixed that while we were ordering (it worked OK without one of the rollers... but might as well get it back to new).
