I am in the process of converting my truck from the stock single cylinder master cylinder to the dual master cylinder. I have picked up the Wagner#F66857 dual type listed in the online manuals but, now I am trying to figure out the proportioning valve/ distribution block.
What proportioning valve/distribution block are you guys using for your dual setups? Someone wrote that the block off a '70 Ford will work. Any others?
Are you using the original brake pressure switch? Or are did you change to a pedal mounted type?
The pipe fittings for this F66857 are much larger than the stock lines. Anybody have any problems with braking performance by using adaptors to reduce the fittings down to the stock lines?

Thanks,
Brian
