I've done mine in stainless and they are not forgiving!!!!! my god what a pain!! but I did it!! both the brakes and fuel. I made my own and they came out great except that I had to buy more line and nuts. The one thing I found out is the nuts on the master cylinder are not replaceable and the go only one way for each tube so keep track of them I threw mine away and found this out and luckly I found them before they were permently gone!! feeding the brake under the engine required removal of the l brackets where the engine mounts to the frame. place a jack under the engine when you are doing this; and take your time. lots of fun!!
