Right, I have all the bits you need, where do you want'em sending?
Quick lesson on Hi-locks though:
This is a pair of Hi-locks:
The blue bolt has a small allen key socket in the threaded bit. Use a spanner on the red coller.
It's up to you but if you want you can make these a permanent repair, all you do is keep tightening until the hex part shears off (It's designed to) I didn't so they will come undone as the shear torque required is quite high and might crush he fiberglass.
The collars have a self locking portion so they are quire stiff. Put a pair of the stainless washers around the blue bolts then thru the outside of the gutter into the front compartment, apply glue/sealant to the reassembled hinge and the get glue all over your hands while you line them up. Once in place and the bolts are thru the holes in the hinge then put the collers on and do them up.
They shouldn't ever corrode as they are titanium apparently.
