Thanks for posting! Very interesting and this is a mod that I can do my self. Just gotta find a scrap Model 3 or Model Y seat!@PatrickTM - here is the tread.
And @acatwith12 Tesla won't sell you the part separately. Yes, they carry it in their parts catalog, yes, they'll fix/replace it under warranty for pre-May 2021 Model Y/3 and all MIC Model 3, but they won't sell it to you if the part doesn't match your VIN. This is one legit criticism of the Tesla store model, vs a dealer/retailer service model.
