Where do I get brake distribution block?

Used might be the most expediant

I bet www.midcomustang.com will have it...you have to call and talk to him though

NPD shows one on page 48 but not sure if it is what you want. You could replace with a combination valve shown on page 46. They are for drum to disc conversions. You didn't say what you had...drum or disc.

if you have a 70 (like me) and have drum brakes (like me) then you have a dist block next to the master cylinder. if this was a disk brake car then it's a proportioning valve.

if you are doing a drum to disk conversion (like me) then you need to replace this distribution block with a proportioning valve. the 69's were different than 70's in that they had the distribution block like the 70 drum car does except they also have a proportioning valve in line as well.

also, on that 70 when swapping out the dist block with a proportiong valve to replace the distrubution block you will find the brake lines enter the dist block from the bottom whereas with a 70 car with disk brakes and a proportiong valve, it enters the proportioning valve from the REAR. making a swap in replacement a pain in the butt when doing a pdb conversion.

does that make sense?

since you have your NEW rear lines I'll assume you got the lines that are for the particular application (front disk or front drum)

yes, i have pictures if needed.

disregard my post. I just re-read original post. Interesting setup.
