74 and up Fullsize Wagoneer/Cherokee/J-truck Steering boxes bolt right onto the frame in place of the existing manual box. Pitman arms from the same should work fine also.
They have four mounting holes instead of the stock three. Common for people to drill and sleeve the frame for the fourth hole although it may not be 100% necessary depending on the application (tires size, hard off road use, and etc.)
You can either fab mounts for the power steering pump from the same donar vehicle, or get a pump from a GM vehicle with the correct mounts already on it for your engine. If you wish to use the hoses from the donar vehicle with a chevy pump, you should at least save the pressure outlet fitting from the back of the donar vehicles pump along with the bypass spring that comes out from behind it. These will screw right into the chevy pump and allow use of the "jeep" specific hoses. Another option is to purchase new hoses, or have them made with the correct ends.
Most seem to skip installing a return line cooler, but I'll be adding one to mine soon. After a couple hours of hard off road driving it will start to foam a bit. A short rest and all is good, but I believe a small cooler would make it a non issue.
