Rear hub, what is it off?

[Cfitzy6]

Good evening folks,

I'm a first time poster although I have been reading for a while.

I rally a 1400 nova in Ireland and my dad is building one for rallying also.
I picked up a crashed rally car the other day for bits however I am having trouble identifying the rear hubs, It has a disc conversion but I can't tell what Hub they used, it's not the Astra one ( tapered bolt pattern).

if any one could help it would be much appreciated, please see the pics below,

regards

ciaran

(I'll throw up one of my rally car too)
