Help - Converted to Front and Rear Disc, now what size for hard lines

[88Stanger]

ok, so i changed out the old drum system to new front and rear disc. now i am looking to install the new hard lines. I have searched and i am trying to figure out what size to use for the hard lines. Mainly to the rear is where i am lost. I purchased a complete front SS kit from Classic Industries, but the rear hard lines, what size? i know there is one line to the Rearend dist. block then hard lined to each disc where it then converts to soft lines. these damn hard lines, what size? I read 1/4" then 3/16" but i need to make sure.
Thanks for your time.
