The driver and passenger seat cushions aren't in very good condition. No tears, but quite cracked. I've been trying to maintain them as well as possible, but I think they need to be replaced. I am sure the foam (or whatever is there) is tired and could use replacement as well. Is it possible to replace the seat insert and not the entire seat? I would probably just order it online because I don't want to be yelled at for going to a junkyard (and leather seats are hard to find in good condition). I've searched online and can't really find much info that's helpful to me. Thanks in advance.
