Does anybody even know what part number this brake line is? Its for an IFS truck, and I thought it would fit mine. Its for 10mm caliper bolts, so I decided to drill it to 7/16. I was going to get some new copper washers to go against the caliper and bolt. I'm afraid that I didn't drill the hole perfectly straight on one of the lines, as you can see in the pic. I also can't figure out which lines I'm supposed to use on which side, or even exactly how they're supposed to line up against the calipers. THE REAL PROBLEM IS that the fittings on the end of these new extended brake lines are simply too thin. The caliper bolt bottoms out before it clamps the line down. So what do I do now? Stacking washers if asking for a leak. I thought about cutting a little off my hollow caliper bolt, but I'm starting to feel like my brake system is going to be very ghetto rigged... not a good thing!!! Can I make these lines work? If not, what extended lines can I get for my '78 k20 corp 10, which has a 7/16 fitting?? somebody please help!!
