Auto zone or any of the parts houses will have what you need. Here's the rub. ...these parts are 30+ years old and have been rebuilt who knows how many times. (no matter how shiny the paint is when you open the box) I just got done putting 4 gear boxes and NINE pumps in my truck and I STILL don't have power steering. The best I did was to mount a Chevy pump to my 300 six. That got me power steering for two weeks. It just went out again tonight backing in to the driveway.

Since my truck is haunted and refuses to have power steering, you shouldn't have the trouble I've had, ...just something to keep in mind.
