Depends on a bunch of things.

The easiest would be to use the stock 914 rear calipers over solid rotors. If you need vented rotors in the back, Eric Shea at PMB Performance can set you up with stock 914 rear calipers with a spacer in the middle to go over the thick vented rotor.

People have adapted 911 rear brakes to the 914 trailing arms, including ways to keep the hand-brake functioning. A search here will probably turn up info on that.

If you don't need a hand-brake at all, you can use the stock 914 front brakes on the rear over solid rotors. You can also make the 911 rear brakes work without including the hand brake part.

And, of course, there are places like Wilwood that make a huge number of different brake setups that can be made to work.

If you're going for a duplicate of the 914-6 GT, I'm not sure what they used. Probably different cars used different setups, but I'm not even certain about that. Check the web site I linked to early in the thread for pictures of what the GTs used, and also talk to Eric Shea (again). "Real GT" or replica of the real GT options are likely to be some of the more expensive ones.
