Bucket Seat Reinforcement Plates

I was getting ready to weld in the bucket seat reinforcement plates on the passenger side of my car and I noticed that someone drilled the holes in the wrong spot for the outboard studs (I am going to guess this was done with the carpet installed). They also drilled holes for the inboard studs, but I cant tell if they are in the correct location, since the dimples are now missing. On the driver side, since I had the dimple locations, I welded the holes that they drilled and made new ones in the correct locations, and the plates went in no problem. Now I am seeing one plate has the thick side towards the tranny tunnel and other is the thin side, they don’t fit at all when turned 90 deg. Below are some pictures of the dimple (Screwdriver) vs. the hole for the outboard and the plates on the inboard. I have seen some people say the AMD parts don’t line up well on all cars and want to double check this before welding them in place.

Measurements aren’t lining up side-to-side and I don’t have a passenger seat to measure. Are the bolt patterns the same for the driver and passenger seat? If so I will just take the measurements from the driver side and mirror them over, if not, does someone know the stud center-to-center distances for the passenger side? (68 Barracuda if that matters)
