if its a 2 outlet rst master cylinder, its an easy re-pipe fitment, im just gonna run my hose to the rear through the bulkhead into the cabin to the bias valve, then back out of the cabin and into a t-piece under the rear seat area, and then to each caliper

all the screw type bias valves available are essentially the same thing, just prices range from good value compbrake kit, to extortionate AP kit which can go up to 5 times the price for a part that does the same job to the same standard lol
