Drum to Disc Conversion Help

I want to begin with the fact that brakes are a big nemisis and this is why I hate messing with them. Installed a disc brake conversion kit on the front of my 69 Barracuda and the brake lines are in need of a switch also so I went ahead and purchased some pre bent lines from Right Stuff (Part #YKT6801. The distribution block needs to be replaced and I know that I will need a proportioning valve due to the fact that disc brakes are on the front and drums on the rear. Ordered a combo valve from Performance Online part #PVC Link(Proportioning and Combination Valve, AC Delco 172-1353 and 172-1361) Of course this block has wrong inlets for the brake line kit. I am stuck at this point and need help on the distribution block as well as a proportioning valve. Thanks in advance help would be great.

what disc brake kit did you use? is it using a factory style parts? big bolt front disc and large bolt rear drums?
