Meanwhile, I got some drawings from NASA HQ years ago and have scans below (click on the thumbnail to open a larger image).  Note that the set of four images (a large drawing scanned in sections) is dated 1983 while the other scan is dated 1985.  The main change seems to be in the solar array lock down points and the change from a long solar array boom to a shorter boom plus a yoke.

1985 version:  1985        Blanket colors:  GRO Colors

1983 version:   1983-4 1983-31983-21983-1
