Hopefully you didn't get the ones you linked to (for GM).
I would've bought the OEM ones myself. I've learned not to trust any of the other brands unless they are track proven (I run Hawks on my Cobra for track work). Not saying these (Centric) aren't any good, I just haven't heard of them before. When stopping an 8000+ lb truck or 20,000+ lb truck and trailer combo, I trust Ford did their homework.
Also, why are you getting mad at Ford because non-Ford pads don't fit? Sounds like you should be mad at Centric to me. I've put aftermarket pads on lots of cars and sometimes they just don't fit. Exchange them for a new set and then they do. Quality control seems to be the issue.
The pads themselves fit, it's just the clips on the ends of the pads that
don't appear to be user friendly. The clips look exactly like the OEM pads
I took off the truck. But getting them back on with "both" clips was just
beyond me. If you got one side of the pad, the other didn't want to go
on. Just strange. When I say "on" I mean a pad loaded with block clips
trying to be placed into the notches on the caliper shoe, before I've
put the caliper back on.
All in all, it works fine with one clip per pad, because I gave up on using
2 clips do to the difficulty in getting them to fit back into the notches
on the caliper shoe. Otherwise, everything else was a easy as pie.
