NA Seat Reupholstery Kit

Back in 2016 I reupholstered my seats with a kit from Sierra Auto Tops & Seats. The original upholstery was mostly fine, but had started wearing away at the usual place on the driver’s side bolster. The restoration was easy and also included a foamectomy and repainting of the metal seat pan bottoms. The vinyl help up well from 2016-2021 when I swapped to NB surfboard seats after refreshing those with another Sierra kit.

This post is reference photos more than a guide. My main advice is to ditch the hog rings and just use zip ties. I took many more photos when reupholstering the NB seats in 2022.

I was very confused where this ring goes when reinstalling the seats, hopefully this clarifies for someone else.
