Help identifying rear differential spider gears

[fire_squatch]

'99 wrangler Sahara
I'm 80% sure I have a Dana 35, but I can't find replacement spider gears that have this rear spline, which suggests to me that a previous owner did something different with it. It has 20 outer splines, 27 inner splines and 15 teeth. I am so lost and just want to get my Jeep on the road again. Thanks in advance!
