I am using '76 3/4 ton calipers on my Dana 44 which use 7/16 Banjo bolts and washers. My stock 10 bolt had I believe had the samll 17 mm. I was told to drill out by brake line to fit the 7/16 line. I have tightened the banjo bolt as tight as I can, but I have a leak from hell both sides. My guess I screwed up my brake line when I drilled it out to 7/16". My option I guess is to get new brake lines to fit the '76 calipers Any comments would be appreciated.
