85 Riviera T Type Repairing Sunroof

Hey guys, I have a 1985 Buick Riviera 3.8 hot air turbo that has a leaking sunroof. I can’t find any info online about where to buy new seals/gaskets to seal it up, does anyone know of a source or have a suggestion where I look? Any input is appreciated, thanks in advance.
Gbody has a redesigned seal kit available.
I just realized what you meant, I hadn’t heard of that website before. I went to the site and found the seal kit, thank you!

I’m not sure if “sunroof” is the correct term, the site calls it an Astro/Moon roof. Anyone familiar with how to install the new seals or have a link to a writeup on it? Thanks
