2000 Pontiac Sunfire GT

Hi, I am replacing the brake lines on my 2000 pontiac sunfire but I am having trouble finding which line to buy since the local shops cant seem to make up their mind. I have done some research that suggests a 3/16″ / 4.75mm line with Metric m10x1.0 single bubble flare fittings. Is this correct? I am replacing the line that goes from the proportion valve to the pass front wheel. The line I want to get already has fittings and is easily bendable by hand. It’s a poly-armor steel pfv line.
