Hello.
I have the rear axle of my cosworth damaged that I had an accident and I need to change it.
Here in Spain I have great difficulty finding parts cosworth and I look like a rear axle from another compatible model.
save someone if crossmenber and rear beam of Ford Scorpio are exactly alike.
Would serve for any model, would have to find the version cosworth.
There some other model than cosworth ford and serve to replace my sapphire cosworth 4x4?
Thanks
