Routed the throttle cable. Notice I had to put the firewall plug backwards because there wasn't room for the cap due to interference with the engine mount. Backwards is okay.
My throttle hole location is only 1/8 to the pilot side and down 1/8 from the Van's location. I moved it because of intereference with the doubler for the fuel line. I would say that is as much leaway as you've got. Any more and it would interfere with the motor mount.
