66 Dart GT HT Whatsitgonnabe?

The lines look made from copper. Are your final lines going to be steel?

I bought a coil of steel brakeline tubing from JC whitney online years ago when doing a 1960 chevy el camino restoration. I think it was 1/8" terne coated steel maybe a 25 or 50 foot roll. I cant remember. It can be ordered with a grab bag of different sized metric or SAE fittings. You will need to double flare it as well. You can also buy the gravel guard all by itself from either inlinetube.com or classictube.com
