Something under the seat is dying

Anyone have any idea what these are from/for? Found the plastic piece under the passenger seat and the metal ring and remains of another plastic piece under the driver's side after moving both seats full forward.
Standard follow-up: how painful will this be to fix?

looks like the bushing and circlip for part of your seat motor mechanism. The bushing is more of a "stop" and if I recall the circlip holds the cable to the motor or the rail sliders. Motor spins the cable which in turn spins the "screw" for the rails for the fore/aft movement. Then again, I probably am totally wrong because I have not looked under a later model seat for some time.

that appears to be a cable housing E clip,
it holds the cable housing from coming loose so the drive cable will stay attached

Thanks, all, esp. Mike for the detailed write-up. Looks like the lower carrier bushings deteriorated, allowing the clip to fall off. Is there a part number for those?

In a word, no, not from Porsche. The gear motors, drive cables, pivot bolts, and height adjusting posts for the seat base are available as spares but the jack screws are part of the seat frame. If any other replacement parts are available they most likely would have to come from Recaro. They made the seat systems for the 928 (still do for Porsche AFAIK.)
Best bet would be to find a set of seats to rob for parts.

While I had everything torn apart for winter maintenance, I pulled the driver's seat and found this on one side

and nothing on the other. This view is of the back of the track. Since one of the front bearings had also disintegrated, I disassembled the drive rod using ammonman's excellent write-up. However, full disassembly is not required to install this part - only the small cap screw under the end of the drive rod has to be removed. I used dimensions from various bushing remains, the drive rod, and the seat frame to draw up a 3D model of the part on TinkerCad. A friend with a 3D printer then printed them out for me.
This is the final result:

Tools required: Metric hex bits to remove the seat and the cap screw under the drive rod.
I can provide the drawing file to anyone who wants to print their own. It does require some intermediate to advanced skill with the 3D printer to control shrinkage, curling, and get the overhang for the circlip right.
Thanks to the folks at 757Makerspace for their help with the prototype, and to Monte at Blizzard Entertainment for the final product.

We have already printed some of these via Rennlist. I measured one & put it into cad a couple of years ago and got some printed for me by a rennlister in the states and posted to me in NZ.
Glad to see I'm not alone in using this technology. I did start a thread about the little bits & pieces on a 928 that were no longer available and could be printed.
Are you able to share the cad file?

If you do not have access to a 3D printer, I have used nylon washers to keep the seat frame from screwing itself too far down on the drive rods and jamming the seat all the way fore or aft.
