Sanger Seat question...

My '96 Sanger is in need of some new interior. I'm having the observer seat, back bench seats, and the two back storage covers re-done. The observer seat feels like it needs some structural help (loose between seat and back).

I'm assuming the base structure for all this is wood. What type should be used? Should it all be fiberglassed. Any suggested do's / dont's before I have the upholstery installed.

Thanks in advance for the suggestions.....

I think Sanger might even sell skins stills for that boat. I also think they will have the composite seat base structure for that boat too. My buddy just had his DLX (I think that's what it is) totally redone with Sanger parts through the mail.

Good Luck!
