The CD is a little fuzzy here. After a lot of scratching I got it. Then I got the backs on and seats set in. Now how to mark them. Then it came to me. Very simple and true. Put a Sharpe in the adjuster hole. Start the seat run from when all the corners a locked in. Then make the run front to back. It is now marked and ready to drill. I had to do a lillte work to get everything working right. Know all I need is a few springs. They have to come out fot the floors so that is as far as I will go now.
