I keep those flex lines in stock for 3/16" and 1/4" line. I can look up the part number this week for you. For frame tabs, I have always made mine, but Speedway sells a kit with weld on tabs and clips. They come Zinc plated which is why I choose to make my own. I don't like trying to clean the zinc off those tiny tabs. I recently found a place that makes them from chromoly for about $1.75 each. I have not tried them though.
