63 dart , mc replace

I too just finished my conversion also. Was going with a Napa MC for 67 Dodge I believe and ended up have to replace lines I was unable to disconnect, stripped the fittings. Ended cutting them up and pulling them out but ran the new steel line back to the rear axle after pulling the old rusted one and used it as a template to make my bends. Lot easier than I thought could not get the rubber one out but will keep soaking it till I an get it disconnected and will replace it.
Smartest thing I did was order the rubber lines and flare fittings and cut my own steel line. Made sure I had all I needed before I began after learning the hard way. Replaced rear wheel cylinders since one blew.
Stops great now and of course wondering if I should replace the 13" wheels and go to disc brakes in the front!
Wow!
