The driver's side front seat on my 1986 FJ60 has a very noticeable sag on the left side. The PO was a big man and he wore it out. Iit is not comfortable sitting in the seat. Furthermore, he was a smoker and he managed to burn several holes in the fabric. I did not find much on the search, so here goes. What are my options? I know that SOR sells a foam bottom replacement for about $150 so I guess option 1 is to get that foam and get new covers which will run at least $300 to $500 for the front. I was wondering if there are any drop-in later model seats that could be found at a salvage yard (later TLC, Toy truck, Tundra, other model). Note: I like the general seating height of my truck and do not want anything with a one-piece high back. Can I pick up later model bucket seats for the same ball park money or am I dreaming. Also, if you have done a seat swap, please include the difficulty of changing the bracketry.
