Title: 73-87 Manual regulator differences - Jason S
Post by: Captkaos on April 19, 2012, 01:45:07 PM
'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.
