Dave, the 23 spline tailshaft would be "technically correct" for your application 70 B/E and you could use your stock 70 B body (1 yr only) automatic tranny crossmember on the 23 spline tailshaft unmodified...if you want to use the 18 spline, thats a 69 and down tranny you have there, different crossmembers between auto/4sp...but you can use your automatic 70 crossmember, you just need to cut open the top welded in structure, and cut off the 70 nose stub where the mount fit (rubber), then purchase a 68-9 mount

Photo below, 70 auto/4spd mount on top, 68-9 4spd only bottom, basically the same, just needs some surgery, on the 68-9 the mount fits inside the open crossmember, either tranny you decide to use will still locate your shifter in the correct opening on the floor


Next question what driveline did the car have before?, what type of automatic 727/904?, what rearend, what are you changing/useing?...

Can I swap the 23 spline tail shaft onto the 18 spline? (curious)
The car had a 383-727 combo with a 8.75 with (489) 3.91 gears but I had a thought of maybe swapping the Dana 60 from my Superbee as that car could use more gear anyways....lots of options! I'm basically trying to use up a lot of stuff I have laying around and really having fun doing this car!!&
