Neo-Geo Control panel dimensions and layout

[neogeofan]

Hi guys.  I am looking for absolutely authentic dimensions and layout information for the Neo-Geo arcade control panel.   I'm not an expert, so if there were different SNK authorized layouts throughout the years I would like to find out about that.  I am only interested in the layouts for machines that SNK produced, I don't want dimensions from hacked up Neo-Geo conversions.  In particular I would like to know the EXACT measurements for spacing and button and joystick placement.  Width of the whole panel, slant angle of the panel, and if there was a curviture where the slanted part meets the vertical front face of the machine, what the radius of curviture might be.   I need this info because I am attempting to produce authentic arcade Neo-Geo controllers for me and my buds.   I would also appreciate seeing photos of the panels if anyone has them.  I appreciate any help that can be offered, thanks!
