3 Result (Pin-to-Pin – ABEF)
4 Subtract D –
To find “D” pick number from chart below that is clos-
est to, but not greater than total from step 3.
Inches mm
3 x 84 = 252
4 x 84 = 336
5 x 84 = 420
6 x 84 = 504
7 x 84 = 588
8 x 84 = 672
3 x 2133.6 = 6400.8
4 x 2133.6 = 8534.4
5 x 2133.6 = 10668
6 x 2133.6 = 12801.6
7 x 2133.6 = 14935.2
8 x 2133.6 = 17068.8
Example–If result from Step 3 is:
500 inches “D” = 420 inches 12,000 mm
“D” = 10,668 mm
