That looks lovely, not much needed on that for concours I reccon, have to say though I don't think wheels suit car IMO, would look better with XR2 "Pepperpots". I say go 2.0 Zetec only needs fabrication of the engine mounts and it's a straight swap just need to sort electronics out for it then.
Nice to see it still has original Ford ignition Leads and your switches to the right of the steering look in tact normally the plastic holder snaps.
