Grady's subtle hint made me realize that there is a difference between the '69-71 CV (thinner) and the '72-75.5 CV (thicker). I went back and discovered I had both types on the shelf. I updated the chart and the photo with the added CV. I also weighed each CV and axle and included that data in the chart.
I am still not clear which axle goes with the the '69-71 thin CV. If I had to guess, I would say it is the same axle as the later 85.5-89 CV. Does anyone know?
Jack....The 85.5-89 has the raised lip as shown on the inner race. The 75.5-85.5 does not have this lip on either side of the race.
