Info is a bit hard to come by, but yes it does appear they are using an E32 HID kit on the Chevelle.

The kits online seem to include everything you need to wire them up (e.g. ballast). It should be possible to wire up these kits to an existing switch / power supply. Mounting them and fitting up any trim pieces seems like it would be the most time consuming. I'm planning on a similar mod to my Firebird, but that is years down the road so I haven't tackled it yet.

Here is an example of a kit available online.
