69 Barracuda Brake Swap

Hey guys rebuilding the front suspension on my 69 Fastback and bought a disc brake conversion kit from POL also changes from SBP to BBP. Now I need to swap the MC and Proportioning valve. What MCshould I purchase if wanting to keep manual breaks and drums in the back with 8 3/4 drums. Also anybody have part numbers for the proportion valve. Thanks in advance.
