I started to clean up the driveshaft and noticed that the original paint marks were still there, under the grey paint someone put on. Some careful cleaning and here's the remnants: From the front of the driveshaft the order is orange, white, then yellow. (This stripe scheme is corroborated by the '72 repair manual list as the correct code for the M-22 and M40 driveshaft for 1972) The stripes are brushed on and they are 1/2" wide with a 3/8" gap between them. (You can still see the brush marks in the paint) The front stripe is 19-3/8" from the front weld seam and the rear stripe is 22-1/2" from the rear weld seam.
