73-87 Manual regulator differences - Jason S
« on: April 19, 2012, 01:45:07 PM »
From Jason S
'73 had smaller rollers (note: some early 1974's had smaller rollers, check) 
74-87 have the same size rollers, but the shaft the handle attaches to is different length. 
73-76 had the same handle shaft length. 
77-87 was a longer handle shaft.

Here is a photo comparison of the 74-76 (74 K-10) on the right and the 77-87 on the left (83 C-10).
Handle shaft length:

Overall dimensions:
