I also dove head first into trying to finish up my brake lines. I can't put into words how angry this made me. I'm a nuclear operator for Pete's sake. I studied this online, watched YouTube videos, forum write ups, you name it. Made about 4 trips to town, hitting all the useless auto parts stores and stirred through all the adapters. JIC, Inverted flare, Bubble flare, NPT, AN........ I dumped probably $40 in useless adapters trying to do this myself. Finally, I was sent to Shelby Auto Parts on Washington Street. This old timer showed me around back and did in 10 minutes what I couldn't in the last week. A truly humbling experience. I guess now I know when to ask for help and I know right where to go. Highly recommend these guys.
