Just an update.
I tried the option of fixing the top of the coils to the top of the housing with a hose clamp and it was all working well.

The coil had been pulled out of place by the hose clamp, bending the metal plate that held it in place. As the spring decided to part ways with the car it severed the brake lines which now have a set of vice grip keeping all my brake fluid off the road.
Looks like relocation cones aren't a bad idea.
