I don't see any lines on the firewall. I have taken a tube (from a roll of monokote and hot glued it to the firewall and then put the cowl on to make sure I have the center lined up. Now I think I can mount the engine and will try what misslieman suggested. Hope I don't screw it up.
Some ARFs have a template you cut out of the instruction manual to mark for engine mounting, usually toward the back of the manual.
