Original seat cover reference / hog ring attachment photos

I recently replace the cover on my passenger seat. Took a lot of photos of how the original was attached. Thought they might be useful for someone else:

This particular seat was made on August 12th, 1981

I’ll be replacing my seat skins by the end of the year, so I’m collecting as nuch info as possible to prepare for the job. I’ll be printing these pictures- Thanks!
