2 Subtract ABEFG –
3 Result (pin-to-pin – ABEFG)
4 Subtract D –
To find “D” pick number from chart below that is closest
to, but not greater than total from step 3.
Inches mm
7 x 84 = 588
8 x 84 = 672
9 x 84 = 756
10 x 84 = 840
11 x 84 = 924
12 x 84 = 1008
7 x 2133.6 = 14935.2
8 x 2133.6 = 17068.8
9 x 2133.6 = 19202.4
