I converted to Hydroboost a few years ago, using all components from the same truck. Unfortunately, I can’t find my notes to tell you what year. I believe it was an ‘86 3/4 ton, but not positive. Also used lines from a 73-87 truck ran down to a combination valve. I have disk brakes on front (slid in a 73-87 full crossmember), and a 14 bolt rear with the big drum brakes.

Brakes work well, but the rear locks before the front, and I would like to install an adjustable proportioning valve. Should this be plumbed in after the combination valve?

Also, I have Wilwood D52 calipers up front and would like to use a Wilwood prop valve, anyone have a recommended part number?
