backing plate ebrake cable guide fixes

[hueyhoolihan]

anyone have an idea as how to go about fixing a worn out rear e-brake cable guide? it's the metal tube that passes through the rear brake backing plate. it's been cut through by the cable at one point in time and although i've got a new cable in there, i know it will fray in no time unless i can fix the tube.

can't find a replacement tube, if there is such a thing. only backing plates are used ones in poor condition on ebay. no reproductions that i can see. unless these would work...

i was thinking maybe soldering in liner or better yet, having someone weld in a new tube of similar dimensions. i'm hoping this is a common problem and people have found a work-a-round for it.

off the wall suggestions welcome.
