corona diffs again

[corollaart]

So i picked up an old rt118 wagon ,thinking that it had a t series diff in it.As i was lead to believe that they come with t series or bw diffs.
But when i took the centre out and tryed in my ra40 housing no way it would fit.So i guess there is a third option any one no???
Im starting to think it could be f series ,but unsure.
10 bolts on the nose of it .
ratio is 4.3
No stamp on id plate (blank)
Tryed to put the axles out corona in to a t series diff ,no chance way bigger.
Stamp on crown wheel:1 1x4.3 06 8 4 R661
Splines 23
any one??
