Brake line and prop valve question for first gen

[importkiller69ss]

I have 98-02 f body brakes installed on my 69. Have the flex lines from Tobin at kore3 I have the right stuff dual 9” booster with the newer style Mc. My question is what brake line kit will work for this setup. Was wanting to go with a pre bent kit . Right stuff says they don’t think there kit will work and aren’t sure if there proportioning valve will work with my calipers .. in-line tube wasn’t sure either. I know this has been done before can anyone help

If you can't find a kit that works you might try bending your own. I used that "new" ni-cad brake line on my latest project. It's kind of bronze in color. You can get different lengths or bulk. It flares like butter. I bought it at Orielly's.
