splines

I just upgraded to chromoly. front Dana 30 27 spline OEM axle shafts. about 5k miles on sealed Spicer 5-760x u-joints. Ran with 32's and an open diff. Includes ABS tone rings but you don't need ABS to use them. The middle part of the passenger side shaft is cleaner because it's been in an 80s...

How many splines (both inner and outer) are the front axles on a TJ Rubicon? Not sure if it's 27 or 30...
