From what I can tell from your post you are learning how to repair things as you go. I would say that you will be best served by replacing all the lines with a pre-bent kit, instead of making your own. Making your own lins isn't too hard, but it will need some special tools for bending and for flaring the ends. Double flaring lines can be tricky if you've never done it, and an incorrect flare can leak. I'll also agree with dan-pa, redo the entire brake system. Most likely you have corrosion in other parts of the system and the rubber parts are probly in poor condition as well. You should be able to get most of the parts for the brake system at the local parts house. I would also stongly suggest that you get a shop manual for your truck. You may have to get 2 manuals, I beleive that the '65 is only a supplement, you may need the '64 as well. Check out American Classic, they have a good assortment and have fast service.
