Rear Axle Brake Line Question

I'm working on a 73 8 1/4 that has no brake lines between the wheel cylinders. I was looking at the tee block on ebay from inline tube, and it says 1959 to 1996. Does that mean I can go to the Upullit and take one off an 80's van. That'd be like 5 bucks as opposed to 35 for a tee block and vent tube from ebay. The underlying condition here is I look for any excuse to go to the junkyard and have fun as opposed to ordering parts from my couch. I assume some of you have this same disease lol.

The second question is on hard lines. A big roll of brake line isn't too expensive and I have a flaring tool, but where do I score the compression fittings. I don't see them anywhere on rockauto under the brake section, or anywhere on the advance auto site.

Thanks guys...
