I had a hard time finding data on it too. But I did finally find the Pershing II Technical Manual online.

Page 116 of the PDF of the Pershing II Technical Manual has some useful missile data. It’s section 5-1 Table 5-1.

First Stage
Length = 144.74 Inches
Max Diameter = 40 Inches

Second Stage
Length = 97.3 Inches
Max Diameter = 40 Inches

Guidance and Control/Adapter Section
Length = 61.51 Inches
Max Diameter = 40 Inches
Min Diameter = 27.75 Inches

Warhead Section
Length = 64.25 Inches
Max Diameter = 27.7 Inches
Min Diameter = 20 Inches

Radar Section
Length = 49.75 Inches
Max Diameter = 20 Inches
Min Diameter = 0 Inches

Missile
Length = 417.55 Inches
Max Diameter = 40 Inches
Min Diameter = 0 Inches

Unfortunately, it combines the Guidance and Contol (upper fins mount to this) measurements with the Adapter (first reduction in body diameter). My best guess from studying images at the measurements for these individually are:

Adapter Section (Estimates)
Length = 17.51 Inches
Max Diameter = 40 Inches
Min Diameter = 33.1 Inches

Guidance and Control (Estimates)
Length = 44 Inches
Max Diameter = 33.1 Inches
Min Diameter = 27.75 Inches

There was no data for the fins, so I originally used photos and came up with my best guess. Pretty sure in hindsight the upper fins are larger than my original build, but I think the lower fins are close.
