You want 3/16" Brake Line, which is the same size as stock, and is most commonly used in passenger cars.
If you are going to be cutting and flaring your own lines, make sure you use a Double Flare! Thats very important, unless you want brake failure and/or leakage
i feel stupid now....lol,honest mistake,anyhow,i have to run brake line's for both the front and the back,from the master cylinder,to the distribution thing,and then to both front,and i know it goes one line to the back,and break into two from the rearend,i am also going to be buying that brake line kit from summit,that actually goes to the caliper's, so another question is,where can i buy the bolts,or whatever they are called for the double flare's,and also what degree flare should i use, thanks alot for your guys help,it is greatly appreciated.thanks again.
