Need help with brake line routing (leaf spring truck)

[MDPotter]

So in between sanding sessions I decided to start installing brake lines. I ordered a complete front to rear kit from GMCPauls (Inline Tube) and according to GMCPauls, the kit I ordered is for my truck, a 1968 1/2 ton SWB leaf spring. The front lines and rear lines all fit nice, but the front to rear line has me puzzled. Where it connects to the rear rubber hose, the bend was too high and would have hit the underside of the bed so I had to modify that, no big deal. But what I don't understand is that the line almost looks like it's too short. With the rear fitting threaded into the flexible hose, the front end, where it bends towards the driver side to crossover, ends up underneath the transmission instead of at the front crossmember with the front lines. Has anyone else had this issue?
