On my 1964 Polara, I have no brake lines, the hard lines. Anyone know the diameter and fitting sizes I need to get? I'm just going with the budget route and bending/running my own lines.
 
IIRC the line size is 5/16, I have lines and fittings at home and can confirm once I get there. Look into nicop alloy lines, much easier to work with and won’t corrode ever.
 
Not to try and thread jack but I’m in the same boat if anyone knows the line sizes for a 67 GTX
 
5/16" is just over a quarter inch, TOO big. 3/16" should be the size, and as mentioned go with the nickel copper lines! You'll be doing yourself a huge favor as these are super easy to work with and they don't rust out.

Thanks couldn’t remember if it was 5/16 or 3/16
 
Think with a single master 1/4" to block on frame rail then 3/16" to all wheel cylinders . 67 Dual master cylinder 5/16" everything, fittings on master different sizes.

I've swapped the single to a 73 A body master.
 
I've done the opposite twice. Joking, my post was meant to confirm what I remember. Would think that to supply 4 5/16" lines more volume?
I'm installing an adjustable proportioning valve so I can tune it regardless. I went ahead and got 3/16 diameter tubing. it comes with multiple sized fittings so hopefully it'll work.
 
Check with the those that know more than me, the drum brakes use the smaller 3/16 & discs use the larger?
