If what you salvage from the mondeo has some sort of end stop switches then possibly (assuming it's a suitable motor :P)

Bare in mind you don't just need physical end stops that stop the motor turning, they need to actively cut off power supply to the motor in their respective directions when the limits of the lin-ac are reached. The controller won't know when to stop on its own and will stall the motor at the limits of movement, which you don't want.

Lots of off the shelf lin-acs have this built in so you can drive them against their limits of movement and they won't stall, a bit like this:
