Mustang II coil overs on '79?

[Mikesbaron]

I've got a line on a set of these Mustang 2 coilovers. wondering what I will need to install them on a 79 coupe?

Coil overs are:
14" extended 10.5" collapsed.
350 lbs springs.

You sure they are off a Mustang II? The front suspension is completely different from that of a fox.
