I picked up a copy of the book you mentioned while I was at the Hershey AACA meet this fall. The book is a nice visual reference for the AFA trucks.
Other than a few pieces of brake line that had been changed recently I have or will replace about 95% of the lines. Once I invested in a good set of Ridgid tubing benders and a double flaring kit I find it quicker and easier to bend and install new tubing rather than trying to rehabilitate old tubing. And the tubing on my 1953 GMC did not have too many compound curves so it was pretty straight forward to bend new lines.
