I bought front and rear SSBC kits and am confused on what I need by the master cylinder. I dont have the distribution block but I have the proportioning valve from the kit. I also bought the prebent stainless line from classic Tube. it doesnt make sense to me on the prebent lines by the master cylinder unless that block is necessary. Nothing lines up and I went to buy the block at Auto parts stores and no luck. Any ideas or opinions?
