According to this article:
http://www.ferret.com.au/articles/z1/view.asp?id=96607 , "the Thompson
Coupling['s]... maximum design angle [is] 20 degrees." They also claim
"no previous coupling has been able to run under load at angles up to
20 degrees," but our _stock_ CV joint will work under load at 20
degrees, and a 930 CV joint is good for 24 or more. Additionally, the
stock and 930 joints are "plunge type," so can accommodate some change
in drive axle length (caused by articulation). I see nothing in the
Thompson design which provides that ability.
