My standard cab had dimples in the floor where Ford would have drilled the holes if it had been built originally with buckets. It is easy to drill them out, it is a PITA getting the front PS bolt started in a nut because there is a heatshield below it... has to be done by feel and right to the limit I can stuff my hand between the cab floor and heat shield.
I have a couple things I don't like about Explorer seats:
1. The drivers side has no tilt at all, the seat to the back angle is preset and is a click or two too far upright for my liking.
2. Since they are almost always power they are intended to be angled off the floor by the power tracks, if they are just stuck on manual tracks they are darn near parallel to the floor, I did not care for that.
3. On manual tracks the slider lever interferes with the bent rod that sticks out of the front.
4. The tall back hit the back window in my standard cab in my regular cab (non issue for you)
