Quoted from kilmarnock1350:
My manual (yellow cover) doesn't specify post locations. It also does not differentiate between metal or plastic posts. Any idea where one gets that info?
Based on memory there are only two physical manuals for the game, the original '81 and '82 LE.
The '84 Classic used the original manual with a different Bally-Midway cover, even though there were wiring color differences.
Neither describes exact post height (or quantity), as you stated, which means it then has to be cross referenced BACK to the actual part in the Bally parts catalogs, sometimes that annotated the parts in a game specific fashion annotation.
That is how it was done during that period for "generic" parts, but was also done often even today with "master parts catalogs" used by Stern.
That is where the information is contained.
I have the parts manuals in my library, but I am trying to give you a direct link to pdf versions which just do not exist, if they were never scanned.
PPS has a version in its weird "book" website application.
Eight Ball Deluxe is the the 1981 Bally Parts Catalog.
The Bally "generic" one is not even listed for review.
Post Long is Bally Part No. C-952-7
Post Short is Bally Part No. C-951-7
If it somewhere else in reference, I have no other leads for the *factory* configuration, as the line up of the plastic height determines the height of the post required.
The data will not be contained in the generic catalog.
If the plastic (clear or screened) is "bending downwards" that mean you are using the wrong post height for that location.
EBD post height normally is determined by the clear plastics locations.
This is not relevant for the post under the left rebound ball gate flap as both work equally.
