In Your Example Your using the Nose of the Pinion - I Guess - for a Plane then
Checking the Working angles of the Joint ..

In the Real World - We have to Pick a Plane - seeing True Ride Height and Normal Load
would be Std . Stance with Vehicle on the Ground .

Hence the Use of that Plane ..

Trig. the Differences over a 43 " or 25 " inch Shaft and the Height Gage doesn't Lye
it's just Simple Math - U Joint Cups - are Directly Attached too & Aligned with Shaft.

In Case You didn't see the T.I.R - https://youtu.be/hCJSTlRw7Jg

I already had done the T.I.R. of those Area's Several Post Back .. Signalling Good to Go . . for Direct Measurements !
