A-body Hemi box 4 speed

I'm not seeing it.
Where is all the factory special 68 SS transmission parts?
How likely is it that ALL these special parts were removed and passenger car and Chevy parts installed as substitutes.
How many race preped four speeds went out of Hurst installed in the SS cars?
How many more 18 spline a-body transmissions were racer built?
How many case castings were made in 68?

Lots harder to pull all the specific stuff out than swap a tailshaft. :cheers:

Everyone had access to lathes in the late 60-early 70's. LOL
