Thanks, that's really helpful. You clearly know your stuff!
You mention it has the wrong steering wheel and gearknob. Could you possibly inform me which would be the correct ones to have? Is it just a matter of colour (red stitching) as if so I don't think they would match the seats which don't have the red stitching.
The gearkknob I could fit myself, but I'm not sure I would be competent enough to do the steering wheel. I have already changed the pedals for proper Ford drilled ones.
