Got any pictures of these brackets that let the seat go back father might want to buy them if you’d sell
Sure thing. I won’t be using them and happy to pass along to someone who will. There are a bunch of bolts that go with the rails, which seem to have locktight on them.
A tip offered to me years ago that I still use in aviation maintenance: In screws or allen heads that are rounded, put a bit of valve grinding compound on the tip of the tool (hex or screwdriver) and the grip improves immensely. I have used this to get numerous fasteners out that wouldn't have volunteered to come out without employing a drill. A small jar of valve grinding compound lives with my screwdrivers and hex set, that's how often I use the technique. Good luck.
Each seating position has 11-12 possible bolts: two on each side toward the front of the car, and three or four on each side toward the rear of the car. Please excuse the elementary photo.
How many bolts and which positions are used in the OEM application? Can you run fewer/more without sacrificing safety? Which positions are people using for aftermarket seats?
Standard configuration is two up front, and four in the rear for each seat. Most seat bolt kits therefore come with one dozen bolts. There’s an extra hole in the rear if you want to position the seat further back.

To use the rearmost holes at the rear mounting point, Porsche sells an extra thick washer which goes between the body mounting bracket and the seat rail 999-025-125-01. So you end up moving the bar with the threaded holes to the rearmost position and sandwiching the washer between the body mounting bracket and the seat.
Thanks all. It’s interesting that 3 of the four mounting plates are removable but the rear, inner most plate has threads fixed in place. Bummer as one of the holes on each side in that position are stripped.

You can use the washer listed above and shift both seats to there rearward holes and you will not have to use the stripped holes. Or you could heli-coil the stripped holes and if that is done properly I feel it would be as good or better than new in terms of strength. Alternatively you could weld in a newly fabricated plate.
The reason there are 4 holes in the rear (also the reason the inner mounts are solid to the floor) is that the seatbelt receptacle is attached to the seat frame. In the event of a head on crash the rear bolts need to hold the weight of the seat as well as the person belted to the seat in the car. With aftermarket seats where the belts are fastened not to the seat but to directly to the body of the car the seat bolts only need to keep the weight of the seat in place in the event of frontal impact. In that case (belts mounted to the body) I would be comfortable using only 4 bolts per seat- 2 from and 2 rear.
