Take a look at the Sexy girl pf in the pictures, specifically the outhole and trough area.
http://www.classicplayfields.com/store-playfields.html
now take a look again at the same area on any of the Bally playfields.
Sexy-Girl uses Gottlieb assemblies. so unless you want to do a ton of cutting to fit all the Bally parts from the playboy you will need to use some Gottlieb parts to do the conversion.
Here is what I had posted to RGP:
The game keeps being billed as a drop in conversion kit for a Bally
Playboy. However the conversions were done in such a way that a
completely wired playfield (built by Arkon) was dropped into a Bally
cabinet with Bally Boards.
So.... look at this
http://www.ipdb.org/showpic.pl?id=2106&picno=41615
The original Arkon playfields (which is what I am assuming was used to
make the CPR repros) use hardware that is all Gottlieb stuff,
gottlieb flipper assemblies, gottlieb drop target assemblies, gottlieb
outhole kicker, gottlieb ball trough, with gottlieb holes and gottlieb
mounting points (even to the point of having the switch diodes on
separate circuit boards like Gottliebs)
Also note that the Bally boards would require the use 43 V for the
coils, but gottlieb coils are 25V so these were probably coils made by
Arkon especially for this kit.
Plus since these original kits were probably made with all new parts
and NOT parts stripped from Bally Playboys will any of the metal
brackets from the top of the pf fit into the mounting holes on the
repros?
Now this isn't to discourage anyone from actually trying the
conversion (I have been tasked with doing one myself) but is just a
heads up that it won't simply be another pf swap like any other normal
swap. You probably could use all the original Bally Playboy under pf
parts but there might be a lot of extra drilling and cutting to get
those parts to fit.
I have several gottlieb pf's worth of parts and will probably fit
these assemblies onto the kit and simply swap out the coils for the
Bally equivalents.
