Well, I’m a bit embarrassed after what I finally learned. First, yes this is an original untouched stock 05 Rubicon DS with 137K on it. At prior posts show, I learned about the molded plastic retention in the joints - interesting and annoying
What I’m really sorry (if I got anyone spun up) about is the (perhaps half assed) way I matched up the new joints with the cleaned up shafts and yolks. I thought for certain the new joints retainer clip groove would not work and that set me to asking what I missed. Turns out what I missed is the I should have just installed the joints, because when I did that this morning, there was a little more play in each of the opposing caps that allowed the clips to fit snugly!
So, short story is the listed joints ARE the right part numbers and they will work on an OEM DS with just a little extra clean up.
Thank for all those who responded with help and guidance.
