I would think that what you bought is correct. MiraclePieCo’s is from an AD truck. Polarbeard’s look like a generic replacement. If it mounts correctly to the three holes, more than likely, it’s correct.
There has to be more TF ‘bolters out there to confirm.
Thanks Phil, that's actually exactly why I'm asking- mine currently only has one hole, but I can't tell if that is because the other bottom 2 are supposed to go into trim or something? I'll get a pic of the area in my truck.
Thanks!
