The type of suspension is called an SLA Suspension. This stands for Short/Long Arm. This refers to the Upper and lower control arms. The upper is usually shorter then the lower and this is done to control Camber gain during articulation. Owens suspension was scratch built by the shop that built the car. Like you said there is no info on the pieces/parts but most of this stuff is available from circle track or specialty shops if you don't want to built it yourself.
I gave you a good design program here...

You won't find anything much better.
Do a search on the web under "suspension design books" there are quite a few out there.
