Mine is a 72 H code with an FMX. Those would be the qualifying factors in the driveshaft selection. The 2 yellow stripes near the pinion end are pretty universal. I cannot recall the exact designation of the 2 yellows. I will see if I can find something. My original buildsheet indicates under DRIVELINE for Driveshaft in Row E boxes 15-22 the following. Position 1 boxes 15,16 LA-Lavender, Position 2 boxes 17,18 R-Red, Position 3 boxes 19,20 DG-Dark Green, Position 4 boxes 21,22 blank.
