Hi, any advice when drivers seat seems to sag more than it should? I have had the seats out in the past, so can manage that. Is new foam or adding a layer of new a difficult process? Upholstery original but pretty good. Is there something else that might cause this? I know this info is likely on the site but can’t find it. Thanks!

Which part is sagging, the seat bottom or the seat back? On the later year spiders, the internal frame of the seat back was weak and prone to cracking, leading to a twisted seat back, AKA "the gangsta lean." If that's what you have, the solution is to take apart the seat back and weld and reinforce the frame.

The seat back has just a little gangsta. Not worried about that now. I mean the seat bottom. Not as firm as the passenger seat. Seems like I should sit a little higher. Thanks!
