I have seen hd flare nuts for 1/4 tube in 9/16 wrench size used by the factory. 1/4 tube would be an OK choice to run to the rear for both brakes if you can get the correct flexible line from the frame to the rear end. Then you could drop down to 3/16 on the individual lines to each side. Neat and simple. If it was me, I'd take my proportioning valve down to the local auto parts store and try fittings until I found the correct combo. Bet it will be simple. Hope all the fraction sizes make sense.

Thanks for the response. I guess I was trying to evade an adapter, but no matter what I think I have to run one. I was searching the Internet and found Classic Trucks ran an article on plumbing their MC on the firewall (

In this picture:
and this one
you can see an adapter (bare steel color) that then runs into the 3/16 line (probably with a 3/8 flair nut), so I will need to locate one of those adapters at my hardware store.
