Need advice on Brake line parts and configuration

I would suggest option 1 as originality does not seem to concern you.

Having the adjustable unit gives you more flexibilty and the factory hold off (or should I say the after market pieces) were barely effective!

Would love to see some more of your Dart as well.

I'm leaning to Option 1 also since I already have the 2 pc front to rear set up, and the original block just needs to be cleaned up.

I could keep it original and get the correct hold down block but I like the idea of the adjustable valve. Plus its Bolt-on.

The new adj. valve should arrive on Thursday so this should be wrapped up by the weekend.
In the meantime disconnect the combo valve and install the old block.
