Hello could someone help me please.? I put a MP master cly on my 1973 Pro Street Duster How do the lines run ? Front line on the master cly go to the top of the port valve and the real line on the master cly go down under of the port valve for the rear brakes ?? Thanks mosweethemi

Any help please ??

I do believe the rear MC port (next to firewall) which always goes to the front brakes goes to the top as you mentioned. Is this an OE 73 dart disc/drum prop valve? You might Google & see if a pic of it will come up with where the lines go

I just checked my 73 Duster with front disc/rear drum and it is as Robert said. :-)

Also, the line from the front port (for the rear brakes) goes to the underside front of the valve. It's hard to see exactly where.

Thanks,
