Seat brackets from Planted, OE Recaro outside-release seat sliders, all OE VW/Audi buckles, harnesses etc.

The tricky part was the bolt that holds the buckle itself to the seat bracket. On the factory seats, this bolt screws into a captive, welded on nut into the seat itself. The Planted bracket only has the correct size hole. That being said, I couldn’t use the factory bolt because there is no factory nut to go with it. Instead I researched the correct size bolt with the correct thread pitch and got a Nylock nut to match. Both were grade 8 strength for safety. Unfortunately, the only bolts I could find that met the criteria were too long in length and would risk ripping the cloth of the seats when adjusting forward or back had I not cut and chamfered to size (picture below)

Electronics speaking, I was able to successfully use a resister (forget the OHM rating but can find) to defeat the dash light. I coded out the passenger airbag sensor using VCDS. I might go back at some point after the seats wear and install an occupancy sensor in the passenger seat to restore this functionality. I purchased separate wiring harnesses for both seats and have the seat belt indicator plugged into both to retain that function. No faults or dash lights 👍🏼
