slant six clutch fork measurment ??

[Princess Valiant]

I know the small block A-body 68-76 clutch fork is 12.5 overall length

but my question is: what is the overall length of a slant six (68-76) and will they interchange

just to make sure .....I am still looking for overall measurement of the clutch fork from a 68+ A-body with a slant six and A-230 three speed.

I know the V8 is 12.5 inches and the OD v8 and slant are also 12.5 and use a ball stud set up.

but I would like to confirm the non-od slant six A-body measurement.

thanks
