what size fittings

napa carries the hard line. that's the easy part. bending to fit makes for a fun time (tip: disconnect the battery incase you happen to hit the post on the starter). comming out exactly right in the length is what's going to jack you up. well worth having a double flaring tool. do a couple practice flares before doing your freshly bent line.
unless your really wanting the stock look, consider steel braided hose w/ AN fittings. i've done both, just redid the hard lines in my car, and hose is much easyer for a quick and clean install
good luck
