MIRACLE Rigging parts

Hi, sorry I know this is mirror fora but we Miracle owners don't seem to have one of our own that I can find...and I bet you guys know the answers to these.

I've been given a Miracle that needs some spare parts but I am fairly new to sailing and not sure which bits I need.
A couple things:
- It's an older model and the mast step isn't locked in, the mast just slots on top of it. I assume the shrouds and forestay, once tensioned, will keep it all upright?!
- The forestay and both shrouds are missing connecting/adjusting hardware at the point of contact with the hull. Does anyone know exactly which adjusters and bits I should buy for it? I just have the wire shrouds with its end in a loop and the plate that's screwed into the boat. No other adjusters, loops, clasps etc.
