Did you get the combination valve, or the proportioning valve and hold off valve? Drum brakes use a distribution block. Drum brake lines from the master to the front wheels are most likely different too. And a new or rebuilt master cylinder for disk brakes. While it is off, check to make sure the control arm bushings are not in need of replacement, as well as the ball joints. It is a LOT easier and cheaper to do that now. If it needs done later, you will again need to remove everything from the truck and do or pay for the labor twice.

I just did a conversion on a 72 Cutlass from power drum to power disk. I also needed the 2 brackets that attach to the frame and hold the rubber brake line and attaches to the metal brake line.. The ones for drums aren't in the right position.

I know you sais you wanted to get it done soon, but you also need it done right.
