STI Six-speed DCCD 2WD Conversion Issue

[ssssly]

Would swapping in a 06-07 center diff to an 04-05 trans work for the adapter or are there other differences besides the diff?

I tried this with ones I have and they do not interchange. The tail casting and more is different. I have the '04 TY856WH4MA and the JDM '06 TY856WB7KA (close ratio with internal pump). USDM for '06 and '07 has same center DCCD diff. as the JDM '06.
Someone on here did the welding and made it work.

I will share my list but it only applies to STi's. I do not know about the Legacy, etc.
