Did the upholstery today - I was off work, and just as well because it ended up taking most of the day to do it. One of the zippers was broken. I tried first to fix what was there, along with resewing the seam, that didn't work. So I had to take the seam part again, and replace the damaged pull/zipper with a better quality one. That ended up taking a couple hours. No word back from Ridies.com on the missing hardware or the broken zipper.
Covers also didn't come with the required wire rods for attachment, so I made them using $$ welding rod
Added aftermarket seat heaters that match the wiring I've already installed. The factory 350Z seat heaters are sewn to the upholstery. No practical way to transfer that, and it would have had to rewire the car to make it work anyway.
Damaged zipper
After first repair, pull tab also snapped off
All zipped up
Sewed over the zipper end so it can't open up on the backside of the pull
Stronger pull
Drivers seat cushion
One self inflicted wound - I miscut the opening for the back release 🥺
Back in car. Plugged the seat heaters, but forgot to test them
