The hard lines to the master cylinder have a different size flare fitting. The hoses are different since they connect to the calipers with banjo bolts. You can use the original front distribution block, since it only serves to branch the fluid to left and right sides.
If you have the money, get the SS braided hoses (they make them to fit the original lines off the dist. block), and fabbing some new hard lines is a piece of cake. The parts are available at most any parts store.
