Best suggestion yet, Thanks.
I have measured carefully each side. Front drivers side - rear suspension to front. And same on Passenger side. The damaged side was appeared as visually pushed back in wheel arch and was confirmed by detailed measurements as 12mm shorter in the wheel base.
I can measure the subframe mounts quite accurately with the engineering equipment I have. But what do I measure to? I can measure the front sub frame mounts and the rear subframe mount but I don't know the correct track width of how they relate to the chassis? Or mayeb how I measure them from a known centre line on the chassis.
My drivers side wheel stands 12mm back cmpared with passenger side and is clearly looks 'pushed back' in the arch. That is what I need to correct.... please any input would be valued?
