I used the DR Diff kit off E-bay and I'm happy with it! Works great. Manual brakes do take some getting used to though....
Isn't the rod different for manual brakes as compared to Power brakes? (on the pedal)

You don't use the bellcrank, only a pushrod direct from the pedal to the cylinder. Is your adjustable rod to long/short or something?

first pic shows power master bracket and you can see how high the hole is
3 is adapter and manual bracket
4 shows how low they mount
5 shows what the manual hole lines up with
bottom circle on 6 shows where it lines up and top circle is where the hole lines up with the power bracket

I took a picture of what I have? Hope it helps? Couldn't get a good picture from under the dash.... In the e-bay listing it said something about the M/C piston being machined for a manual push rod..?
