Bob,
The late Gary Helland has a good article in the Garage section of the Manx Club Site dealing with rear suspensions.
Jon Chabot of Topline likes to use an extra long bolt to get the torsion tube cover plate aligned so the other three bolts holding the plate can be inserted. Once everything is compressed in place he removes the long bolt and replaces it with the correct length.
The Baja Bugs and Buggies book by Jeff Hibbard also has some good descriptions.
