Lateral-g Forums - 1st gen Camaro subframe dimensions

It seems this is the most common dimensioned drawing for the 1st gen F-body cars. While this is a good reference, it seems there is some information missing.

Does anyone know the correct dimensions for the following:

-The distance from Body mount no.1 (firewall body mount) to center line of the front wheels / axle (at rest)

-The distance from Body mount no.1 (firewall body mount) to the radiator support mounts

-Does the datum used for the vertical dimensions represent the ground (assuming stock ride height and rims and tires)

-What is the vertical dimension from the datum line to the top of the front frame rail (radiator support mounting surface)
