Korps,
Most of the time there are two vertical lines on the firewall. One is the center line and the other is the off set line for the thrust. Your motor mount should be set up on the off set line and as long as the end of the crank is on the center line your ok.
There is one horizontal line about a fifth or so from the top of the firewall then there is one vertical line going down. In the picture both dashed lines can be seen on the firewall.
