There is excellent agreement between ratio of the height before the first bend of the
I7Bs and the 90 degree angle of the foot.
The width of OT2 is 123 caliper units
The length of OT2I7B is 543 units

This is interpreted as when an assumed width of the OT2 is taken as 123 units =
0.75 inches a calculated value of 3.31 inches is obtained
D9 (Dynodon reports a measurment of 3.5 inches (post 56 Jan 23 2011)
A discrepancy of about 6% which is probably acceptable given the non critical nature of the part.
