help w/ Yukon axles & thrust spacers

Im trying to remember the details---but i had a set of Yukons that were in my 742 case with clutch type sure grip. It was recommended i remove the thrust button so they would engage the splines deeper? Sorry its been a while---

I did that while the pig was out to be sure.

Mine measured 27.75" from the splined end to the back of the big flange. Green style bearings



The answer can be found at moparts--the screen name DoctorDiff . He's the Yukon dealer where i bought mine .

Sorry i cant remember the details---------STUPID ALZHEIMERS !!
