I would keep it simple and make acurate OP6502(18/19/20) Case set for PAM 001A, 002A, 003,A 004,A 009A, 010A - covering a lot of options.
Gen parts - with the exception of all the dials can be sourced no problem - they key will be acdurate materials , artwork and CNC.
I have Gen 002/009 , 001/004 and 003 Dials and there are Gen PAM 010 dials out there.High resolution images and measurements would not be too much of an issue.
Good luck with the project!!
