Here's the exploded parts view of the outer clutch controls from the parts book and a cross-section view of the inner clutch controls from the '65 shop manual.
This vendor deals in clutch linkages for mid-60s GM intermediates among others:
They may have suggestions as to where to obtain a complete kit or individual pieces.
This linkage design is closest to that used on '63-66 Wildcats. 7-digit part numbers starting with a 1 usually were a Buick design. 7-digit part numbers starting with a 3 usually were a Chevy design and may have better availability.
Thanks for responding. I need the parts closest to the clutch housing. I have the 364 engine rebuilt. Now found a 4 speed clutch assembly I am trying to make happen.
I am in need of a schematic and/or parts from the throw out bearing out. UPDATE - Turns out this housing is a 1963-64 Wildcat and/or 1963 Lesabre... View attachment 8988
