Chuck:
Sorry that I did interpret your request quite clearly.
You can, however, deduce the information that you seek from what was presented,
as the intrusion will be the same as on the top. Be mindful that the Connector
Plate is wider than the forerunner E05 22 Connector Bracket. The total
intrusion will be about 4.8mm (1.6+3.2) from the 141mm side so you could be
working with a total clearance of 131.4mm, considering the intrusions of the
screws. This placement of these screws on the side, rather than on the face,
was suggested as a simplification of the cover, which has been a bear to
fabricate.

Hi Dick,
I must apologize for not being very clear about what
PEM/screw I was referring to. Its good that you thought of the one you did as
that is also important. The one I was referring to is labeled 2 (with a circle around
the 2) on drawing E05-62. Its the screw that attaches the side(s) of the lid to
the connector plate.
Sorry for the confusion,
Chuck
