Tuscan Rear Discs

[TUS 2 CON]

Anyone know if these would fit a standard 2005 4.0 Tuscan (not S)?

The rear discs that are on the car at the moment aren't drilled or grooved btw

Sorry, I've just looked at the car again and the rear discs are drilled.

I was looking around for alternatives because I'm sure someone has told me in the past that the rear discs were off a Sierra Cosworth
