Check everything before installing.

Pretty cheap parts are used, bad install on the heli-coils, thin castings and the aluminum is soft. Probably best to buy them bare and do the rest yourself. The box they come in is pretty thin too so it would be better if Jegs would put them in a box too so they don't get damaged in shipping and need surfacing like mine did.
