AD20.5 Big Pivot Question

[OldGrandDad]

I have a question I was hoping the group may be able to help me with. As my AD20.5 collection has grown, I'm looking at swapping scales on a couple of my big pivot AD20.5's (as well as potentially ordering some new scales). Is the titanium 20.5 the only model which has a different big pivot (with the extra material to fit in the titanium scales)? Do all of the G10 and carbon fiber models that come with the big pivot use the same pivot?
