Looking to buy a front driver side hard line. Oem part number GM 10307911. I tried buying 3 of these online and got refunded 3 times. If anyone has one out knows where I can get one please tell me.

If the line is that rare a find, you may need to fabricate your own replacement locally. I've had good luck working with local 18 wheeler truck shops in the past making brake lines for foreign or out-of-production vehicles.

Good Luck in your search!
