Product review (3 stars): I recommend removing one of your old cams and checking the ...
As noted by others, the holes for the screws are large. The holes in my old parts were for a #8 screw. The holes in these parts are over 1/4 inch (9/32). They provide one #10 machine screw with a shoulder per side - which they show going into the door to hold the upper cam (did not fit my door). Not sure what you are suppose to use for the lower cam.

If you install the cams with the old screws in the large holes, the cams rotate back and forth (due to the screws not fitting the holes). The door makes odd noises and doesn't work smoothly. I rummaged through my parts bins and found some rubber grommets that fit the holes in the cams and took up the slack. Works OK now.

I recommend removing one of your old cams and checking the screw holes before ordering. Look for a part that matches.
