Identification of rear end?

[ATHiker]

I have a 2000 wrangler sport, I am trying to ID the rear end. I have heard it is either a dana 35 or 44. I got the following numbers off the rear cover and an attached tag. (Cover) DANA 43225, 189 9, rev K, 022797. (on Tab) 52111760AB, 3 07 5993 Do these number mean anything and can someone ID the rear with these #s Thanks Randy Bethlehem Pa.

Should be a D35 with 3.07 gear ratio. I don't think the D44 was available with 3.07 in the TJ.
