    You can use most of the newer ones. They will physically bolt up - but odds are your master has SAE threads, and the new ones have metric, so you'll probably have to get a couble of metric flare nuts and a flaring tool to make it work.

    I took a master from a '93 K2500 and bolted in onto my '91 crewcab. I'm not saying its 'correct', but it works just fine. /forums/images/graemlins/wink.gif

    For a '74 Blazer, I'd check to see if a '91 Blazer is aluminum - if not, go with a 92 - it will be aluminum for sure.
