I recently swapped a dana 60 and 10.25 onto my 86 and now i want to install the master cylinder and brake booster from the same f-350 . The brake parts are 1990 and it has an integrated proportioning valve. The valve for the 86 is on the frame so I don't think bolting the 86 brake lines up to the 90 master cylinder is going to work. This would give me 2 proportioning valves in my system. Will an 86 F-350 master cylinder work with a 90 booster? Any one have another idea?
