Guys,
Here is the website for the group doing a "continuation" of the Cheetah.

The diff and trans tail stock are connected with a u-joint...no drive shaft.
There is a great Hot Rod Magazine (March 1964) article on the Bill Thomas Cheetah that I think I found at the ClubCobra site...would attach the pdf. file but I don't know how...sorry.
Pete
