In the past there was a company called MacPhat Studios that sold a cockpit upgrade for this plane. The link in the store is dead and according Coolsky this company does not exist any more. I found about this kit on this forum. There was a topic about it dated 2013, so a very long time ago. 

I would love to have this upgrade. I do not know it it is illegal in this case to ask if somebody could help me with a copy of the highest resolution blue panels . The reason I want this is to ease my old eyes with better readable labels on the panels.  If not possible, is there a way I can "overhaul"  them myself  ? I have done this a few times in Xplane but I am rather new in P3D and files seem to be scattered all over the  filesystem. 

This plane is sold for use in P3DV4, but I use the plane in P3DV5.3 and at least upto now it seems to work perfect. This amazing plane has so much features that it will take a while before I tried them all. Together with the PMDG DC-6 and A2A Connie my most used plane.

Actually is sold for use P3DV4 + , it applies to P3Dv5 as well, but only if you buy the "Ultimate Airliners DC-9 and Super 80 MegaPack" .

I bought it two weeks ago and I'm loving it. 👍

I bought the megapack, around the same time, but before I did I mailed them if it was suited for V5. He answered me it was upto V4 and never tested in V5.But I have more V4 planes, and even FSX planes that run fine in V5. Often most things work fine, the things that not work are upto now not a real problem. The installer does not give you V5 as option. I wanted the DC-6 so I had to do some things (followed a video) so V4 installers now think I use V4. That works beautiful.  Because I want max studylevel I wanted the Leonardo, but that needs 8GB Vram and I have 6. Then I found the Coolsky and took the gamble and I love it. I only need better resolution for labels.
