Changing individual gear ratios?

Taller is that the ring gear side by side the XD is taller than the Yaris ring gear

Oh, yes, I noticed that too. If you just put the diff and pinion shaft in, they will scrape against each other. If you install the center housing and put the retaining clip on the bearing, it lifts the pinion shaft up a few mm, which should give plenty of clearance.

I was looking in to parts for my XD tranny 2 & 3rd syncros, and notice the the 3rd gear is the same for most toyotas with C5X, 2nd gear is for the XD and 09+ corollas and the 1st gear is unique to the XD. What can be the difference in them?

I'm not sure I understand what you're asking for. The difference in gear ratios, the difference between part numbers for identical rations, or something else?
