Proportioning valve advice, confused where to go from now Options

[Hammy]

So this "quick" brake fix job has turned into another real headache. (IMG:style_emoticons/default/smile.gif) What's new?

Screwed up two of the rear brake hard lines when I was replacing the rubber lines. So we went down and bought some new metric hard lines at a FLAPS, they fit nicely, blah blah blah.

Now it appears that the threading for the right brake line IN the proportioning valve is stripped, and the brake line will screw into it but has a lot of play, is very loose and basically will for sure be leaking. (IMG:style_emoticons/default/huh.gif)

So now what do you think I should do? I've already spent so much on this brake fix job and I would *really* hate to spend 200 bucks on another P valve. The adjustable ones listed on PP say they're for track use only too. What about replacing with a T fitting? I've read of others doing that. Street car, stock brakes....

Thanks for any help...
