Another gearing question

So, I couldn't find an axle tag on neither the front nor the rear axle.

I tried counting the number of drive shaft rotations, in relation to one full turn of the wheel...and I got almost 5 complete rotations. Going off of that information, my best guess was that it was 4:88..to preface this, I have limited knowledge in gearing so, feel free to correct me!

I pulled the front axle cover this afternoon, I've got the following information from that, as it's on the ring gear in this order clockwise.

DANA 17483 A3B84 438 (Could I be mis reading that as 488?) I don't like to guess which is why instead of just going with the counting, I pulled the cover.

Then there's a red portion of the gear that either says M200 or M Z00.

Any thoughts and opinions are appreciated.

 

I would think there is a space or other punctuation between the 43 and 8?

43/8 = 5.375 or 5.38 rounded. That would be correct for a 50's F head equipped CJ5.

Do you have a picture of all the numbers?

 

Mark and count the ring gear teeth......
