How do I disassemble seats 190E?
 

I am home for Christmas for 30 days so I thought I'd take care of a few projects. The first is the seats. I'd like to separate the tracks from the seat to clean and rebuilt them. They have accumulated a bunch of junk and do not slide easily. I'll also be replacing some of the weatherstripping in the doors. What do you guys think about an Avantgarde grill?

Thank you for any advice or tips.
