any suggestions on how I could install a shut on my old nacra 5.7?

I'm sure it's been done a few times.
I've done that to a G-Cat 5.7.
Most of the hardware was from Murrays for a Hobie 18. I had the sails custom made sized for me to single hand offshore, and a guck snuffer. For stock sails you could go with hobie 18 stuff. The jib I have is from a hobie 18 it needs to be cut down just a bit yet so I can sheet in tight and I rebuilt the jib bridle so I have a roller furling jib. I can take pictures and more specifics on the hardware if needed. Also I have a website www.themanshed.com
The G-Cat is loads of fun to sail and single handle with a spin!
So doing it to a Nacra couldn't be much different.

I added one to an SC20, used a windsurfing mast for the pole, and cobbled together a snuffing system. I've been buying the SNU snuffers from Dennis Key for the last couple of upgrades, and can recommend them highly. Lotsa F18 chutes out there for sale, best results would come from a new spin custom built to the dimensions of your particular boat, but its more money.
You'll never go back to sailing without one once you've experienced it. Oh, maybe to an A cat....
