Over the summer I had to replace the front brake line for my 77 550. It took a lot of searching and editing through the confusion to know which parts to order. I called the good tech guy at Dennis Kirk, and he helped me put together a list of parts to use.
I added a post to my blog, which is linked here:

Thanks and I hope this helps,
Jeff
