True he will need 2 separate sets of brake lines...1 for front,,,1 for rear
But what I'm saying is the brake lines dont care what kind of brakes you have..they just move fluid...your either connecting the flex hose to a caliper for disc ,or a wheel cyl for drums...doesn't matter what kind of brakes you have..
The master cyl does matter....if he runs drums he needs a drum/drum master cyl
If he switchs to a disc/drum setup he'll need a disc/drum master cyl...
I gather your looking for brakes lines that "fit" the truck...but parts stores carry premade brake lines that you can bend to fit...if you need them cut to a specific length a brake shop can cut and reflare the line for you if you dont have the tools...I have my own flare tool...I buy the long premade tubing from oreillys and a handful of threaded fittings and build my own....
