We are finally going to start building the chassis for my coronet this winter. My question, to show how long this has been on the back burner, bought the sfi book in 2009. Anyone know if anything has changed. Should I buy a new book?

The only update was this year! They added docol r8 to the material list!If you plan to use 4130 or docol I would suggest and go to 25.3 spec! Not that much more work since you are already back halfing the car!
