Which power steering pump should I get?

Well I just went through this last week. The 340 / 360 is no problem at all. If you want it bone stock that might take some doing because I beleive the pump is a Federal and that was hard to find for me. So I blew that off and said to myself "self go with the Sagianw pump". being a cheap SOB I go down to my local pick your part (my Disneyland)and roamed around for any Dodge 71 or older. Sometimes this place has some older Dodges. After roaming around and finding nothing I came accross a 1986 Chrysler 5th Ave. The hood was up and as I walked by I looked in just for kicks and noticed that it was a 318, with power steering etc. So I get to looking closer and sure enough everything except the high pressure hose were exactly what I was looking for. One good thing. So I took all the brackets, pump (Saginaw) and high pressure hose, paid the guy 30 dollars went home and put everything on and it fit perfectly. However trying to be clever and save a buck I decided to take the slide valve so I wouldn't have to buy a hose. Because the hose was the only difference in the whole setup. Thats when it happened...... You can see what happened in the topic "oh man Steering problems"
