Rear axle brake line toooo short???

Just tried to install the rear axle brake line set. The drivers side piece seemed to fit pretty good but when I layed the passenger side piece up over the 8/3/4" hump into the clip the arc of the line fit the arc of the rear end perfect. Only problem is that the line is about 2" short of treading into the vent block on the rear axle? Do you think the package was marked wrong and I got one for an 7 1/4" axle??? It is really way short but fits the pumpkin and back of the passenger wheel just fine??? I am puzzled??? Don't have the old one to match. Got them from Rite Stuff Products? They also sent me a mislabeled fuel line for a 111" car. My Demon is 108"?? Anybody else have these issues??
