ljrdburke, R.C. Outlaw still posts occasionally, he has chanced his handle to "Livewire" I do not know what if anything he may have in the way of cockpit pieces.
The ones I got from him were really old 9 years ago. You might want to check I fly Tallies or other suppliers. I have resorted to getting my instruments off the internet
and scaling them to size for the panel I am working on.
Good Luck!
