Worked on fitting the upper firewall and bow. The factory firewall flutes are not matched to the holes in the bow, so I basically had to straighten all the flutes and then re-flute the firewall to work with the holes in the bow. This was a lot of trial and error, because I had to have the flutes in the correct locations, but also had to have a straight firewall (the depth and placement of the flutes impact how the metal warpes and bows).
In the end I got it worked out, but as usual my fluting is not very pleasing to the eye. Luckily this will be well hidden from view. :)
