Brake questions

Ok I asked about the master already (67 Fairlane with drum/drum) so now for the rest of the line setup. Here is what I am thinking as far as distribution. One line out and down to a distribution block that splits to driver front and pass. front. Other line out and down the drivers side of the tunnel instead of pass. side to the rear dist block which should already split rear drivers and rear pass. Is this correct? Any chance someone knows what sizes of line to use? Also what sizes the junction to rubber is from the factory? Thanks for your help.

I'm pretty sure my 64 Falcon was 3/16". If you're making your own lines, or even buying pre-made lines and just bending to fit, get some of these! Conical crush washers. Same material as on a caliper hose connection.
Don't get me wrong. If a brake line is absolutely perfect it will work well perfect. But if it's just a hair off, these crush down and make a perfect leak free fit. You get them at a hydraulic line type shop. Royal Brass in San Jose, CA is where I got mine.
