Longer rear break hose available?

I replacing the rear brake hose and the one I ordered is too short. I'm working on a 73 Duster with an 8.25 rear axle and when the rear suspension is fully extended the new hose is way to short. I'd say 3-4 inches too short. I've looked at hoses online for other cars and there are different part nos. even though the hoses look the same. Only thing is they don't give the length of the hose.

What vehicle should I order for in order to get a longer hose?
