print the drawing and get out your scale and carefully measure the paper distance of the 2.000 dimension. Calculate the ratio of Measured / 2.000.

measure a missing dimension and multiple that times the ratio, to get an approximate distance for the missing dimension.

Jack has a good answer, but skip the printing step.
Screenshot, or export an image from the PDF.
Import Into SOLIDWORKS as a sketch image
Scale as needed for 1:1
Trace over the image.

Attached is an image of what I did. Dimensions are included.

There is something wrong with the drawing though. See the 1.732" dimension in the top view? Why does the same diameter measure 1.5" in the right view?

There should also be a thread callout to define the threads.
