XY but modern?

[71XY]

ok so was sitting down with dad the other day and we where thinking about ideas about the XY and we where throwing around the idea of buying a 2005 XR8 or turboed XR6 and putting all the running gear and all that in it but im new to fords and heard that you need all the radio and dash for the ecu to run and all that also what modifications would be needed crossmembers all the drive line gear also woundering anyone done it before???

Cheers
Mike
