So, I picked up a new Willwood adjustable proportioning valve for my 69 coupe, and have ran into a snag. The original hard lines at the original proportioning block come out to the front brakes through a 3/16 brake line using a 1/2"-20 count tube nut. I originally wanted to just buy a matching 1/2"-20 female to female coupling that will allow me to use a pre fabricated line from Napa to adapt this 1/2 inch line to the wilwood (3/8"-24) block.

Does anyone know where I can find this oddball sizeed 1/2"-20 3/16 tube female to female. Or any suggestions?

I could just use the tube nuts that came with the wilwood and cut/reflare my lines to the 3/8, but I dont want to.. (laziness) Ill probably end up having to do it anyway.

 

3/16, not 3/8

That's what I did, a lot cleaner. Look on the bright side, once you flare it on, you only have to do it once.

 

Oh well. I guys that's really the only proper way.. hopefully I can rent a flaring tool.

 

Went back to napa and decided to just buy some more pre made 3/8 (3/16 tube) lines and just replace what I had. Better choice in the long run and it all works properly. I like the wilwood adjustable bias unit. Very nice!!

 

It is, and has the pressure activated brake light switch.
