Hauled home a 720 special today

:trink40:I found a 720 special,a little rough around the edges,but I think its worth saving, It is missing the steering box,and a few shrouds for the dash, Does anyone know if an automotive steering box could be easily adaptable?,or if I should take this opportunity to put power steering on it? The tractor came with a front blade ,60" mower, and a 48" tiller. here's some pics.
