The fittings are m10-1 Inverted flare. Another website has some pretty detailed pictures of a good patch job. My car was originally from massachusetts, and last weekend when I put braided lines in, the rear lines popped. I am waiting for an m10-1 x m10-1 brake union...they are suprisngly hard to find. You will want to get NAPA tool SER 161A to flare the lines that you are going to cut into.
It shouldn't be too bad of a job.
