power steering pump swap

i have a 78 cj5 with 258, early full restoration, the old ps pump was installed wrong, the pivot bolt was not put in and the pump was pulled onto the manifold and melted, i obtained a replacement pump from a cj8, i think an 83 with 258 as well and brackets, it looks like it will bolt in. can i straight swap this? the newer pump has a second small pulley in front of the larger one, what is this for? i bought valvoline dextron3/mercon atf for this, is that an appropriate fluid? the pressure hose to the steering box is in poor shape and i will have to replace it, the attatchment at the box is in a nightmare spot, do i have to pull the whole radiator to get there or do i just have to put my head and shoulders in the engine compartment, sorry for all the questions, thanks for any help, derm

Both pumps should be the same, however, you should be able to swap the tanks. As for the pulley, as long as the driven groove is the same size and lines up with whe belts, it shouldn't be a problem(the second groove is probably for an air pump). If the grooves don't line up, then pull off the pulley(with the proper puller) and swap them over. Be sure to pull the pulley back on using a bold in the threaded hole in the shaft. Good luck
