The CR drawings all in all are not too bad. Some measurements are not production friendly, but can be converted using a meaningful "datum-line". The front lower suspension mounts come to mind.

The birdcage needs to be bend "to fit" into your body. The birdcage around the door frame openings are for aluminium bodied cars only.

The fibre body cars have a different tubing where you attach the door locks, if I my memory serves me well.

The angle and radius of the scuttle hoop is extremely critical, especially in the windshield and door hinge area.

The actual height of it seems to be confusing, but Mickmate will have the accurate value for you. In fact, he should make you that piece!
