These pictures show the alignment jig and firewall secured in place with M4 screws and nuts. The Firewall is between the back of the fuse nose and the alignment jig. The steel rod through the middle is used to set the side thrust to 0 degrees. A digital angle gauge is used to check the down thrust setting. To adjust the thrust line, shim washers will be placed between the firewall and back of the nose ring. These will be left in place permanently whilst gluing the firewall in.

Cheers,
Jason.
