Here is a link with several setups. I'm not thinking of the shifter linkage. I am looking at my kickdown linkage from my 70 Duster and it is adjustable like that, well it was before the manual valve body.

Check the side bar pictures of the two bottom drawings and you can clearly see the adjustment. Those are for mid 70's transmissions.
