Another Jeep steering shaft question

[atm70chevy]

I've been doing some looking about installing the Jeep Cherokee shaft in our trucks. My question is will this only work on 73 and later year models? Mine is a 1970 and every post I can seem to find is on a later year model..... I have also seen a few posts where people have used shafts from Astro vans. Can someone help clear this up for me please.

Thanks,
Anthony

This mod is done on g body's also..
So I think box spline count/type is the key..
I think the 76 up truck box is the same box input shaft spline as the later g body, and astro/jeep..

Thanks. So I need to count the splines on my steering box right? Sorry for the dumb question.... This is my first build.

I have an astro shaft here for my g body..
I can look and see if I can get to it and count.. it's kinda buried in the garage . but if needed I can go there this week end and get the spline count on both ends.
or if the column end is a d shape..
