We have received a number of request about this installation and are going to
work on a detail write up with photos for PDLJMPR (if they will take it:-))
The brief version is the adapter plate is just a piece of 1/16" sheet aluminum
cut and drilled to fit the foot well opening. You can use the blank off plate
on the passengers side as a pattern. The adapter plate needs to be flat so
just using another blank off plate will not work. New bolt holes have to be
drilled in the footwell to accommodate the '67 master cylinder assembly (67
mca). These are located by aligning the front edge he 67 mca mounting bracket
with the front edge of the adapter plate. The 67 mca will straddle the
adapter plate. The 67 mca is wider and shorter than the footwell opening but
the only critical part is where the peddles pass through the footwell. With
the 67 mca and adapter plate aligned mark out and remove from the adapter
plate the area for the peddles to pass through. The primary thing that the
adapter plate does is cover up the footwell opening. Bolt the adapter plate
with a 1/16" cork gasket to the footwell then do the same thing with the
master cylinder assembly.

We did this change over about 20 years ago so do not remember for sure but we
think we kept the same brake lines.
Hope this helps. If you ever head over to San Diego lets get together.
