Rally car air conditioning!
On the other side of the vent appears to be some cloth fabric material to act as an air filter.
The interior was refreshed with a pair of modern Sparcos. Sabelt harnesses go along with the seats to hold the occupants in place. For those of you who have not heard of Sabelt, they are used in the very top level of motorsports such as Formula 1 and Le Mans. If you ever wanted to know the history of the Lancia Delta, there is apparently a book on the subject available.
Dashes were much plainer back in the 80s. The navigator’s computer on the passenger side reminds me of something, well, from the 80s. In the upper right of the dash is a pressure gauge that the navigator would have been responsible for keeping tabs on. To the left of the computer are easy access fuses in case one popped.
A nice big tach is mounted in the middle of the instrument cluster for the driver. I’m a bit surprised the tach goes up to 10,000rpm as I don’t think this engine can rev anywhere near that, though I could be wrong. The only other two gauges are for voltage and what I think is a fuel gauge. Warning lights are used for fuel pressure, water temperature, oil pressure, and alternator. The big gauge in the center stack appears to be a boost gauge.
