Procar seat brackets awareness

I jumped on a chance to buy the Procar seat brackets for my 1968 Barracuda because JEGS had them for a good sale price. The 81340 and 81341 are listed as the suitable Procar part numbers for this model year ('65 - '69 inclusive). When they arrived, I checked the fitment and was surprised.
The first 7 photos are associated with the driver's side of the car. The remaining 3 photos are for the passenger side of the car. The silver coloured markings on the floor appear to be where holes would be drilled for bucket seat brackets. Clearly, the brackets do not fit.
Fortunately, the people at JEGS were very helpful. They took these photos and brought the matter to Procar. There was no useful information at the Procar site so it required a phone call with a Procar tech to sort the matter out.
Per Procar, there were two different floor pan model numbers for my car in the given year. I am not sure how many other Mopar models did the same thing or for how many years this happened.
Procar has the 81344 and 81345 for my model year too but you would not be able to determine this easily. Summit lists these as unavailable and JEGS does not list them at all. They are available elsewhere but the stock photos are generic and unhelpful.
JEGS is making the issue right by paying for return shipping of the items and selling the correct ones to me at the same price ($78 each) as can be found at other sites.
I hope the images and measurements therein will prove helpful to others.
As always, caveat emptor!!
