yes, my car has a 2X6 from the firewall back to the kickup at the rearend, that is laying on the frame wtih the body bolted to it. the car was really sound so i left the wood in the car. just removed it out of the doors because of all wear and tear the doors take. plus i removed maybe 50 lbs out of each door using 3/4 inch tubing and 20 guage metal. i could barely pick up a door when i removed them off the car. i can pick them up now easily now. and you can grab them at the top and bottom of the back of the door an try to twist the door it will not move. all my door with wood in them will flex top to bottom after they are used. jonathan
