T3: f/i diffs between '68 and '71?

[A bear in his natural habitat 16-Mar-1998 1444 <burden@rhett.ENET.dec.com>]

A friend (net-impared) has a '68 Squareback with the stock f/i.  He was over
our house this weekend checking out our '72 Bus and noticed the other '71
Squareback we acquired.  It has the stock f/i as well and he was wondering
if the parts will work on his '68.

So, what f/i parts from a '71 will work on a '68?

Thanks
