Yep, works out nicely.   And, the larger input shaft and sturdier '64-65
box is a plus as well.

I know someone who did this, simply by removing the diff yoke bolts to let
the yokes slip in and out a tad ala the earlier diff.    Then again, GM did
this with the '65 Greenbriers which use a '65 car differential but slip-in
yokes.    There's also a fitting for attachment of the speedo cable which
looks odd on a late diff.   

I've not been inside a '65 Greenbrier diff but I assume it's simply fitted
with earlier parts ala the pinion shaft with speedo drive threads and the
earlier center section parts with no threaded holes for the yoke bolts etc.
   Now I need to go check the manuals and see...
