it will kinda depend on what your plan is for the truck. nobody is gonna fault you for installing a dual cylinder on a classic "built back to stock" truck but if you plan to do other changes, like changing to an engine with more power, IFS with disc brakes or a differential and rear suspension change, etc then really think about what you will NEED for brakes. a go fast truck with stock brakes is kind of a bad choice. brakes should always outperform the power. if thats the case then you will need to decide if you want a firewall mounted system or a frame mounted system. hydro boost will deliver the best brakes and be a small package but you will need a power steering pump to supply the hydraulic side of things. if you are doing a simple master cylinder change to get a dual system then choose one that came from a truck with drum/drum brakes. i think some of the classic truck online stores sell a master cylinder that is a near direct fit but all will require some sort of do it yourself fabrication for brake lines and possibly a pushrod.
