I have a 67 big block and I am installing front discs off of a 70 chevelle. I was wondering if any one made front brake lines that would work with this combination or do we need to make lines from scratch to make it work.

I don't know if this will help but I have a 67ss with front discs. I picked up new hoses from NAPA from the line to the caliper and they were too short. We picked 67 impala hoses and they work perfectly. I can't answer if you mean the hard lines.

if you need to buy the lines for a 70

I did this same conversion. I got everything I needed from 'the right stuff' in Ohio. It all fit fine. (Hoses and Lines)
