I've started the brake conversion on my 64. Front disk ,10 drum rear 8 3/4 . I also have frame rail connectors and Torque boxes front and rear. I'm wondering how some of you that have a similar set up ran your rear brake line tubing. Did you stay under the crossmember. I really don't want to drill there in fear of weakening the torsion bar socket . Doesn't seem to be any provisions. Unfortunately I don't remember how the originals went thru. 8 yrs ago lol. Looking at my literature it doesn't show much. I'm guessing most ran under the frame rails. Thanks
