50th Ann. Vt upgrades

[Isrum_isgood]

G'day all. I recently bought a 50th anniversary vt sedan and was looking at putting in some fancy stuff like the Berlina instrument cluster and possibly the climate control unit. Are these items "plug and play" or do they take major modifications. Cheers

Instrument cluster is plug and play, climate control is very major modification, dash out and change heater box and quite a few other things.
