So, a buddy of mine talked me into a '76 GL1000.
As he and I have been getting it road ready, I started digging into the seat (or it started digging into me!)
After some research, I identified it as a Hang Two seat. There is no rust on the pan, so I though a replacement cover would be a good option. I know this seat fits the bike and is comfortable. I just want the look to match. I have no intention of having a bike that looks like it will fall apart. She sat for 5 years after her first owner passed (I am the 2nd official owner) and she was showing her 80k miles, but was well maintained.
While I can't make out all of the text on the sticker, I was able to get GL1000 TMC-00 as a partial model number. You can find lots of two ups and Saddlemen has a replacement cover, but I saw a couple of their finished products and was less than impressed. SO, more searching...
I ran across B&H Specialties
https://www.motorcycleseatcovers.com and gave it a look.
They have the following seat covers that may be of interest:
A GL-1000 Stock Seat Cover (Part# 11-27-00)

A GL-1000 Hang Two (Part# 12-00-50) - 7" back

A GL-1000 Hang Two (Part# 12-00-51) - 9" back

I sent an inquiry in and Shirley Newton wrote back:
The 1978-1979 has a 9 inch back. The back being from the bottom of the seat (above fender) to the stitch line of the back bucket.
The 1976-1977 has a 7 inch back.
They both have the same diamond design design sewn in.
I have a final question out to Shirley about he size and will order when she gets back to me.
I'll keep the post updated as I move forward.
