Hey all , been awhile since I have posted here.
Question, on my diff I have 39F stamped on the top and bottom. Does that mean 3:9?
Its a 52 P23 and I understand they came with the 3.9 with a 4.1 as option in hilly states.
Any clues?????

Should be. Easy way to confirm it. Jack up one rear wheel - place a mark on the driveshaft and have someone turn the wheel one complete turn. The drivesshaft should have made 3.9 turns in
the same time frame....
Thanks, will try that next.
The 39 is likely the number of teeth on the crown gear. As the pinion has 10, the ratio is 3.9 to 1. As for the F, I have not seen that before. With one wheel still on the ground, rotating the other wheel will turn the driveshaft 1.95 ( half of 3.9) turns because of the action of the spider gears. Rotating the wheel twice will give you the correct count.
Thank you, next time its up I will try it and see.
