Hi there,
I have just been through this with my 2wd saff, the 2wd cortina ones fit but they are quite different, the impellor is much larger on the cossie one and has a flange on it, outside the cossie one has thicker webbing and a larger diameter snout.
Over here in NZ / Oz my local tuner said if you use the cortina one you may run into heating issues down the track.
(Cossie on left, Cortina on right)
(Cossie closest and Cortina furtherest away)
Also there is reconditioning kits available if the impellor isnt to badly rusted. I did also manage to find a reproduction waterpump that had the cortina housing with the cossie impellor. End the end I just orderd mine through Burtons and got the proper OE item.
Hope this helps,
Cheers,
Kane
