You may be able to adjust the brackets, Dick, if looseness isn't the issue. Seems like some of the screw holes were slotted. But as I recall the screws were in there pretty good - it may take a "big gun" screwdriver. I think one of my brackets is actually missing a screw, but it works okay anyway. The scissors apparatus has to mesh just right in the center so the detent holds the dimple, but when I tried micro-adjusting mine it wasn't particularly easy. Bending things can make it worse, and stress the pivots; plus you don't want the apparatus snagging up on the air bag or anything else in the door frame when it closes.
It was some years ago, but to my recollection BCS' second fix was to replace the scissors altogether.
