Yep, you have a long water pump. There are 2 differences in them as far as power steering pumps are concerned. One pump (I don't remember the year range, but I believe it is late 70's) has a threaded boss there on the drivers side where the PS pump mounts. The other has just a smooth bore hole. The lower bracket for that pump will have a nut welded to the back side of it. Another thing to be aware of is the different fitting styles for the hose connections. The pumps and steering boxes prior to 1980 have an SAE inverted flare fitting. After 1980 they used a metric fitting with an O-ring. The conversion goes a little easier if you have both the pump and steering box with the same fittings. The pressure fitting in the back of the pumps can be changed, but you will have to have the one you need to switch to, so you may as well switch the whole pump.....unless there is something wrong with it.
