The only issue I've had with the generic kits is sometimes you need to take a drill bit one size larger than the holes to make the roll pins actually go through. Just depends on luck. But they otherwise work great. Makes lifting heavy implements like our 800lb chipper solid as a rock, no rattling around in the hitch.
One more thing to note, is that you may need to get a PTO extender, to extend your PTO shaft about four inches, the extra width this hitch puts the implement back by. Depends how much overlap is on your shaft.
