Farmall H power steering

i just purchased '42 farmall h with a wde front end and front loader
A friend told me it would be a good idea to put a power steering unit on it
are there factory or aftermarket units where are they available?
good ones - ones to stay away from??
do they bolt on or is fabrication needed?
what parts are needed to make sure it is complete?
what price range do they go for ??
