I won't be correcting every single thing; some because I think I lack the skill or ambition to do so and a couple because you won't be able to see them anyway. For those interested, following is a list of cockpit related items that can be corrected to make the MkII pit a MkIa pit:
The lower right of the IP should have two fuel gauges. (I won't be correcting this.)
Rudder Pedals should have cloth retainers at the top.
The Landing Lights device should be on the lower left of the IP just to the below right of the Brake Pressure Gauge.
The kit instructions are wrong when they say to paint the gun firing button all red. It should be brass, with the ring around it in red.
I am replacing the seat with the Barracuda one. It has the correct seat back cushion and the armor plate. Also I will not be installing the Very pistol cartridge holder to the front of the seat.
I will make a radiator flap lever. This goes on the floor just to the left of left rudder operating rod.
I won't install part 36, the IFF destructor panel; they were not installed until after BoB.
I won't install parts 37 and 38, VHF radios were very uncommon during BoB.
I will be installing all the Barracuda AM cockpit stuff, as that is all accurate for a BoB period Spit.
There is very likely a few other things that I have missed as I am not an in depth expert on the Spitfire, but I think I will be able to construct a pretty accurate pit with what I do know. Of course I am all ears if any of you have better or more accurate knowledge then I do.
On to the photos of what I have done thus far.
Overall shot showing most of the pit parts. The resin parts are all Barracuda, the white, beige or darker grey parts are what I have scratched as is the wire of course.

IP showing resin compass, IP cabling and the Landing Lights switch.

Pit side walls with resin and scratched parts.

Rudder Pedal Assembly, the beige colored pieces are extensions I made. The very nice Barracuda Control Stick.

The seat bulkhead with the insulated cable I made using a piece of plastic rod drilled out with small pieces of copper wire that are installed in the voltage regulator.

I drilled out all the lightening holes, probably won't be seen, but was an easy task, so why not!
