Ok, I had a long old response typed up it was “lost”. Here is the abridged version. Converging the lower links is known as a Satchell link and is totally different than C4L the Chevelle and Mustang use. The Satchell link has a much lower RRCH due to the converging link that define the roll center being located below the axle rather that above it.
The only advantage to using a PHB over a Watts link is packaging. A frame mounted Watts link allows RRCH to remain constant through range of motion and has a lower unsprung weight.
Steve, the Satchell link controls pinion movement the same way a C4L does; through use of the the parellel links and somewhat through the angled links.
