Recently bought a 1985 Custom 10 with excellent body and shot straight six. Put in new straight six and moved the shifter (3 speed) from the column to the floor. Steering wheel touches my belly with the seat full back. There is no cup holders or storage for new cd player's cds. Truck feels like it's going to rollover when I corner. Had bench seat rebuilt but still sags on right cheek due to poor job and poor design of seat. The bed has wooden boards which I would like to replace but only see kits of oak, pine, or wallboard paneling. Can I use treated lumber to replace them? Old truck and i have a long way to go, but I could sure use some input on the steering wheel, wooden bed, cab storage, sway, etc. Thanks guys.
