Yoke size

I acquired a yoke for my a-727 yesterday. We are upgrading our /6 '75 Duster to a 360/727/8 3/4 combo. I was pretty sure of what I read here that I could keep my drive shaft but probably have to lengthen it.

The dimensions seem to be off.



Will the universal take up the difference in width or is there another small 727 yoke or do I need to toss my drive shaft as well ?

You input is always appreciated.
