Measurement LH RH Description
A 26-7/8 to 27

B 26-15/16
to theoretical
27

C 40-1/4 40-1/4 see photo
D 40-3/8
suspect at least
1/8 too much
40
40 to 40-1/4
is believed correct
measures 40-1/2
on diagonal to theoretical
E 1/4
this is 'suspect'
1/8, or 3/16
to theoretical
I trust the RH side
I had to re-fab the LH
F Edge 2-7/8 2-11/16 measured to bottom
edge of firewall
F Break 8 7-13/16 measured to 'corner'
of toe panel break

The 'theoretical' is the imaginary edge if the sheet metal was bent exactly square, with no radius in the bend. In other words it is the intersection of the two planar surfaces which define the edge. I did not measure to the 'tangent of the radiuses'.

I clamped a parallel to the top of the sill and measured straight down to the bottom of the parallel for 'C' and 'D'. I did not measure diagonals, except as a reference in the description for 'D'. I don't have a picture for measurement 'D', but it was done the same as 'C'.

My body is off a little on the LH side, and is high about 1/8 inch, I believe.
I tend to trust the RH measurements a little better than the LH ones as being proper.

Above is the upper rear of the RH door opening for measurement 'A'.
27 inches to theoretical.

Pic above is the lower front of the RH door opening for measurement 'B'.
27 inches to theoretical. The scale is at the same height as the top of the sill, as defined by the parallel.

This is the lower front of the RH door opening for measurement 'C'.
40-1/4 inches. Parallel is clamped to sill and measurement is to bottom of parallel.

This is the lower rear of the RH door opening for measurement 'E'.
In this photo, the gap is about 1/8, or 3/16 inches to the theoretical of the bracket.

This is the lower RH front mount for measurement 'F Edge'.
2-11/16 inches to edge of firewall.

This is the lower RH front mount for measurement 'F Break'.
7-13/16 inches to break of toe panel.
