Picture of the dash, no radio was installed and the hole still covered in leather. Heater knob is sourced from an Austin Mini--or more correctly, the entire heater boss is a modified Mini Innocenti series I box (modified for the intake to come via a 'chimney" from fresh air from the cowl vents instead of the rights side). The motor is not a Smiths, but a maker I can only identify as in Asti, Italy). The hamster wheel fan blade may be common with English Austin Mini or Rover.
Hood mat decoration as used on the trunk on a Ghibli spider.
Note the decorative pattern on the door gaskets. I'd have expected Ghia to use the same weatherstripping between Ghibli and Mangusta, but as I can tell the Goose used something common with Fiat 500 and others and Ghibli weatherstripping becomes the gasket around the rear wheels.
Pedal box cover removed; owner spliced in local Fan relays. Brake reservoirs shared with VW beetle, I hear (and used on early Pantera).
Spanish Ayacsa AC evaporator box is real wood 
,million dollar question is still to understand what pieces were shared with it contemporaneously but it looks like Alfa Spider basically used same Behr design for another 3 decades.
