Insight on new '67 rear brake hose not fitting?

I bought a Raybestos 24058 rear brake hose from Rock Auto to replace the old one on our '67 Dodge Dart 270/225 automatic. Come to find out it's not long enough to fit in the mounting hole and to reach for the back brakes. I actually bought 2 hoses before realizing we only needed one replacement, but either way, both of the hoses aren't the right size.

The previous mechanic that worked on the car for my Aunt just wired another brake hose into the mounting bracket and used the shorter hose, but it's not the safest alternative in the world by any means. We'd like to get one that actually fits.

Can anybody give me any help as to what hose to buy? My friend that's a mechanic tried to match them up the other day, too, and after ordering a couple and them not being the right size, either, we need some help. If anybody has run into this problem and can let me know what hose to get that will work, I sure would appreciate it!
