Plumbing for Wilwood rear drum to disk conversion?

So I finally got around to putting my rear drum to disk conversion kit on my '68..trouble is, the fittings on the dynalite calipers are 1/8 NPT and that somehow needs to go to 7/16 x 24 on the hard line on the chassis. For the life of me I can't figure out how that works..doesn't seem like I can go anywhere from 1/8 NPT..any suggestions?

You buy the appropriate adaptor. They come in different angles, straight, 45 deg 90 deg Usually 1/8 PT male to -3 or -4 male, then use the appropriate flexline to connect to the hardline. Usually you completely redo the entire line set. I wouldn't buy from Wilwood as they are way over priced, Summit will be your better choice.

Ok, so now I've gotten it from two 1/8 NPT lines tee-d to a single -4 AN line. I don't think there's such a thing as a -4 to 7/16 x 24 adapter (can't find one), so I'm thinking ill cut the old fitting off, put a -4 line nut on there, and re-flare it. What do you guys think of that? Also, I know the help you guys can give is limited without pics, Ill take some today and post them. EDIT: Turns out they do make those. I figured it was something dumb that I missed.

Just have flex hoses made to fit both ends, they sell them, usually braided stainless steel. For a clean job make new shorter hard lines and use the braided lines to the calipers.
