No More Power Steering...

Well I bought a pair of Hedman headers for my Duster with a 318 in it. They were "supposed" to be compatible with power steering, but guess what, they aren't :banghead: This is the second time I've yanked headers in and out of my car, first pair was my fault because I bought the wrong headers, but these should have worked! I'll lose my sanity if I pull those headers out again. So I'm trying now to find a manual steering box and just ditch the power steering. Does anyone know of a place that sells used manual steering boxes? Still in high school and trying to pay off a 900 dollar speeding ticket so I don't have a big budget at all.
