71 Duster Brake hard line size?

[smartken22]

I am getting ready to make all new brake lines since I am doin a full resto on the Duster. I am trying to order the new tubing, but I am not quite sure the tubing size. 3/16 or 1/4? Thanks for the help.

If you have an old piece from the car put a 3/16 and 1/4 open end wrench over the line and that will tell you.

3/16, but around the valve and MC, they change some fitting nuts to 1/4, and other off beat crap. Save the old ones in that area, we played hell finding adapters, and making own lines in that area.
