I don't know how tall your firewall is, but the thrust line is defined (if you can find it) as the top of the upper longerons, although I'm not entirely sure that's clearly stated anywhere. I figured it out from side views. Older newsletters mention 2.375" below the top of the upper longerons a time or two for different engines, and that's where mine is, because the Corvair fits best there...
