How easy would it be to swap the headlights in an '87 240 wagon with the pre '80 circle lights?

What type of wiring is needed?

Also how easy would it be to swap the instrument cluster with again, a pre '80 instrument cluster?

Im sure that would be harder than the front lights because there are more relays in the newer versions that would just sit and not be used, and so on...

I dont see it being that hard of a swap....
Check out turbobricks, for they might have a writeup on it.
