Hi guys, I need to replace the seals on my W116 (77 450SEL)

And looking at the store, there are many things and not ure which i really need... 1977 Mercedes-Benz 450SEL Sedan - Seals & Weatherstripping - Page 1

Are the Meyle seals good?
What is the part 210-671-03-97 for? Do I need it? And if so, how many?
There are many glue and adhesive options ... I'm lost on which is required.


Thanks.
