Summit carries a whole host of brake plumbing fittings. Being that they now have a warehouse in GA, it should only take a day or two for you to get what you need. (Wish I could remember what size banjo bolts those are to help you out!!)
www.godmanhiperformance.com also carries a lot of plumbing stuff. I have never ordered from them, but I have used their website as a reference to see if something like what I am thinking exists and then I do comparison shopping.
