1969 Dodge Dart GT “driver” build

You don't need the stock valve-it's not very good, anyway. An adjustable proportioning valve is better-they're less than fifty bucks.

Speedway Black Adjustable Brake Proportioning Valve

I have one and would rather just use the factory stuff (factory stuff worked fine in the other car)

Again I'm just trying to answer your question as to why the rear brake line came up short?? I still believe the line that you show is correct for factory 1969 disc brakes (B41 on the fender tag). A factory four wheel drum brake car doesn't require any proportioning value in the rear line so therefore a slightly longer line is required. This is what 1969 engineers designed not me. Until it was pointed out to me and I looked at the FSM I was unaware about any difference. On another note the rear wheel cylinders are also different part# from factory drum or disc. If my memory serves me one is 7/8" the other 15/16" ??
Regardless keep on doing what you're doing cause you're doing a great job. Like your co-pilot by the way.

I believe the red 69 dart came with something like this (I swapped to the adjustable valve after I swapped to disc brakes circa 2001). The yellow car didn't have it and the factory line went all the way to the valve. Stole the picture of the car with the 17" crown vic wheels from another post (not my kid :poke:) Thanks for all the kind words.

After further research I thought the distribution block was the proportioning valve.
