Do you happen to have the original fittings still? I have a '72 and had to get the brake line custom made. There is a place here in Las Vegas called All Hose (link below) who can make pretty much ANY kind of hose. They will even use your old fittings if they're in good enough condition. My two hoses cost around $50 to make and it was done in a day. I'm not sure if they do mail in orders...but its worth a try for a guaranteed perfect fit.
