Rigging info requested for 1970 Balboa 20

Purchased a 1970 Balboa 20.
Mast, Boom, Cables seem to be good shape.
The rudder is from a different boat and installed backwards, once I fix that it should be fine.
No lines, and a box of misc blocks.

Does the Balboa come with a swing type rudder?
Any rigging info or guide/manual would be appreciated.
