how much is involved with swapping the dash in a MB with one from a hatch?

Stuff all. I've done it with a VX Hatch dashboard and all it took was changing the mount in the rear of the glovebox, messing around with the heater controls and lowering the steering column.

As long as you have the heater controls, or the MB ones fit in your set. You may also need to do some re-wiring for the loom to fit...

Good point. I forgot to mention that I had the Hatch cluster loom as well, which just plugs straight into the MB loom against the firewall.

Thanks guys, the wiring loom was my main concern
