904-090
May 15, 2004
Catching
back up on 090. After repairing 090's dash, Jack is doing
the final fit. This will be glued in when the car is righted.
Mark spent his last days at Gunnar finalizing the metal work
on the rear tail support.
The final
pieces are welded in. These areas on 904's are always damaged
from careless floor jack jockeys.
The center
structure fits perfectly.
The area
where Mark is welding was definitely a weak link on 904's.
The tail was just too heavy and made too much down force for
the rear structure. In a perfect world, this structure is
a little less than adequate.

I am using
this pattern of the front wheel arch from 904-068 because
this car had never been damaged in this area. On 090, the
wheel arch on both the left and right side were heavily modified
(flared fenders). While we repaired the car, we replaced a
lot of the front fenders, so a correct fender opening had
to be remade.
When I
replaced the fenders, I left the edges long so I could add
the 14mm edge which gives the fenders strength. Here, the
pattern now fits the arch perfectly.
Tape is
applied to create a ledge that I can brush with cabosil and
then add four layers of mat to make the perfect lip.
The picture
on the left is the headlight opening, which was damaged from
one crash or another. Although it looks a little rough, the
shape is now perfect and the hole will be cut out after the
fender is painted.
A skin
coat of filler was applied and then sanded before the texture
(mat) and joining straps were glued inside the fender.
The frame
is roughed up so the mat strap that attaches the bottom to
the frame will actually stick. The picture on the right shows
the 1-1/2 oz mat that finishes off the inside of the fender.
The driver's side will be done next and both fender arches
will be primed black.
