Just got some bucket seats from Pullapart from a 93 XJ. No rips, just two small cigarette sized holes in the driver side one. Also, naturally the bottom seat bolster is worn down and sagging a little on the driver side one. I'm a little hesitant to open it up, but in consideration, can anyone confirm if it's just foam I have to add/replace, or if there is like a metal wire that is broken or something. Honestly I'll probably just leave it how it is and just give them a good clean, but I'm just curious what it would take to fix it. -Thanks
