CEN GST converting w/center diff

[tashpop]

i've done some searching, and the part i have from stock diff output is gs039. the rear cup appears to be gs094. in the tr arena, its front and rear ouput cups are gs094. with this info, i'm thinking i can just pick up a tr areana''s center diff and replace the front output with a gs039 and it should be a direct swap. if anybody knows anything that would make this not work, please let me know so i don't waste any money and time going this direction.
