Geen bearing install

Ain't no button in the new one. Detriot Trutrac 4:10 built by DTS.
I WOULD like to get the button out of the factory 3:23. I see springs, so I guess it's a cone type posi. I think that means I have to tear the unit apart to get the pin out. Am I right? Hope I'm wrong.

Put 140 miles on the new unit today and going from 3:23 to 4:10 is a pretty dramatic difference. Won't be doin' much highway driving in this thing. What a jump in performance, though. 6000 RPM comes REALLY fast ...all of a sudden.....
