I had trouble getting the master to bench bleed properly. Then I cross threaded the Blazer PV, so it leaked.

Then I decided I wanted more adjustability so I bought a brake bias valve from Summit that allows me to reduce the rear drums down as low as 52% or anywhere above that. The brake bias valve is badged as "Summit" but underneath the badge it has Wilwood cast into the metal. So it's really a Wilwood product.

I cut the ring off the Blazer booster push rod and tapped it. Then used a Speedway pushrod extension with HEIM joint. I drilled a new hole on the pedal arm for the pushrod to bolt on. That reduces the pedal sensitivity a bit.
