Take You're time, I started at the wheel cyl.side and worked my way to the block get a bender like truckernix said there cheap and easy to use , if you have the old line set it on the work bench and use it to reproduce a new one bend for bend as long as the old one looks right and fitted right.
Also if you're having trouble getting the lines in after you bend them you can remove the wheel cyl feed the line in and then bolt the wheel cyl back on and bolt the line in .
