Here's some work I did on the cockpit staring with the armour plate and head rest.
In the actual Typhoon the cockpit harness shoulder straps wrapped around a horizontal bar that was mounted on the armour plate. Here's a pic of Nicky showing how they were done.

Also, here's a drawing of the actual seat used in the Typhoon.

Also,
The Aries cockpit doesn't provide any detail here so I had to scratch build the area.
I cut out 3 brackets for the harness bar using plastic sheet then pre drilled the holes with a small bit then used a larger .5mm one that would allow the plastic rod to slip through. As you can see they have a pointed end on them which I will sand and round off make them look more in scale.
For this scale, rivets of the correct size are not really possible to do by just cutting off pieces of .5mm strip rod which is the smallest size you can get for instance in evergreen plastic. I have a number of different size rivets that I purchased from Masterclub for detailing my models and I did initially try .5mm rivets above the harness bar but they looked over-sized compared to the picture i was using as a reference so I went down to a .4mm rivet from Masterclub and they looked spot on. I kept the .5mm hex rivet on the top plate as it looked good by itself. These rivets are absolutely tiny and very hard to see. A steady hand was required to get them in place.
Also, the cockpit seat has a seat adjustment level on the right side as well. I suspect the left and right ones adjusted forward/backward movement of the seat while the other adjusted height.
So I scratch build the right hand lever which I will add last when assembling the cockpit to the airframe as well as the armour plate and seat.
The final picture shows the left and right cockpit side walls painted up, the armour plate complete and painted, the firewall and cockpit seat. Aries did a good job on the seat as it is fairly accurate.
