Center Diff Pins

My new revision 1 pins, EN30 steel, hardened to 60HRC, ground to size, titanium nitride coated, multiple spiral oiling grooves force fed from gearbox oil bath. Made in standard size and 0.2mm oversize for replacement where gear internals are damaged, in this case, the gear internals, centre diff case and centre block are ground to the correct oversize. Also tool steel retaining pins.

So did you get any other work done to the diff or tranny, or did you just get it all shipped back to you stock because it already had the new, upgraded pins? Just wondering because I have a 2011, and I would love to not have to upgrade the pins when I do my clutch down the line.
