1939 Buick Special Camber adjustment?

[MajesticDean]

I was just wondering how to adjust the camber  settings on the front suspension of my 1939 Buick Special

from 1940 shop manual, likely to be similar for 1939:

 

Camber
If frame dimensions check as given in "Frame" section,   and    Front   Suspension    parts   check 
according  to  limits  in  "Dimensional  Drawing" section, camber setting will automatically  come 
within  the  limits  given  below.   Therefore,  no camber  adjustment  is  provided  on Series 
80-90 front  suspension.   A  special  upper  control  arm eccentric   pivot   pin   is   available 
  for    use   on Series 40-50-60-70 under Group 6.178, Part No. 231760 to be used where camber 
corrections are desired.   This eccentric  pin should  be used  only to correct slight errors.  
Camber readings which are  outside allowable  limits indicates that parts are  bent  to  the  
extent  that  they  should  be  re­
placed.
