'64 Barracuda front brake lines

My general experience with Dr Diff is that the customer service is excellent, but that the part quality and qc is sub par.

Though I don’t have specific experiences with his brake lines
i can't remember having an issue with anything I've bought from him, but I agree 100% on the quality of customer service. That's why he's on my short list of "Who do I want to give my money to..."
