I just dropped a 454 in my 87 monte carlo and am trying to get the 87 power steering pump on the engine, my question I have found 2 late 70's big block trucks with all the pulleys and brackets will the late 70's p.s. bracket match with fine with the 87 style pump? I know they changed the lines a little but not sure about mounting points? Also can I resuse the pulley I take off the older power on the new style? I believe they both are a press on style
