Just to give you a start a 70 Buick Muncie still had the 10 spline input shaft.

9785581 = 1968-72 Buick 350, 400 and 455.

A correct 70 GS 455 Muncie will have the TCS switch in the driver's side with the terminals exposed.

Your trans appears to have different year parts:

thanks for the help you really put me at ease
i bought the whole 4 spd set up right down to the sterring column
and was told it was out of a 71 gs so this is good news as im not goin to start on it for a couple of months and the doubt was killing me

A 1971 input shaft should be a 26 spline count.
