I posted this over on KLOV as well and would like to help with this project
theres still some work that needs to be done to this to make it more true to the original
The "graident" is not only wrong, FYI "graidents" dont always print correctly as you see them and the orginal was a 
halftone  print that pretty much went from top to bottom 
from about 90% at the top to about 10% at the bottom
not to pick but heres a quick comparison 
original scan in the center latest "cleanup" on the right

the cabinet background art should be a seperate vectored layer
with the proper 
halftones and a 
bleed added to the the cabinet shape for an easier install since it will be impossible to fit it exactly.
A few other small issues Midway logo is crooked, and the MK logo isnt a perfect circle 
its a little stretched out of shape and the monitor bolts should really be removed
So no time is wasted on whats allready been done 
Do you have the laest CLEANED UP version of just Johnny and the Dragon without the cabinet?
the one I show on the left is from one of the posted stages of cleanup before the "gradient" was added.
and 
silkscreened control panel box art will be finished VERY soon.
