I have a 99 Yukon 4 door, 4wd. The brake line to the rear in the frame rail blew. I went online looking for new prevent brake line from the fron to the rear including the rear anxle"The fronts are good". I have looked every where but all I find is complete front/rear kits, axle alone and right offf the master but not the one in the rail. I have tried classic tube, inline tube, rock auto and many more. I do not want to start making my own. Can anyone help? Thanks
