Thanks for all the comments and keep them coming.
Regarding the red line on the tach, The factory spec for the 1970 engines shows 6700 RPM for the E model (see attached from the little spec book). The Tach in my car had a 6500 red line before I started and I had North Hollywood replicate it. I have no reason to believe the tach was not original to the car, Date codes on the tach matched the other instruments. I would think the red line should match the spec book. Not sure what to do about this one just yet.
JB....Not sure what might be wrong with the basket weave on the dash. The original fascia pieces with the original basket weave were restored with new material. See the before pics. I am not sure I see any differences.
Jim...We did not touch the floorboards since they were in very good condition.
