Cheap & easy Power Drums? '66 Signet

Found this piece on the 'bay, looks like all I'd need to do is install and bend/fab some brake lines to get it all installed? Currently I've got manual drum/drum and power steering on a /6 car, so this makes sense to help driveability.... Not a poorly spent $120. Any problems with install or compatabilitiy I might see? Cheers!
