duster dude,it says the booster is for disc brakes.Does it matter that he has drum brakes?

I don't "think" it matters.

only thing that should come into play for disc or drum would be your master cylinder and you proportioning valve.

and you shouldnt have to change anything since you arent converting to disc brakes or anything.

only thing you will need is the booster
