Yet another brake question. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I know there has been several discussions here about which brake line goes where but I still have some confusion. My 65 has two sizes of brake line. On the original single reservoir there was a big line that went to the front brakes and then split into a smaller line to the back. I bought a master for a 67 which has two different size holes and I put my larger line in the larger port but that puts it at the rear of the master and I thought the front brakes were supposed to feed from the front port. Will it be okay this way or do I need to get some adapters and swap them. It is standard non power drum brakes.

Take your master to the parts store. Get nuts that fit in the ports. Front port to front, rear to rear.

With the '67-'70 master cylinders, the front port is the front brakes and the rear is rear brakes. You will need either adapter fittings or change the lines accordingly.
