Can I swap HVAC controls in 95 Caprice wagon for Roadmaster controls? Whats involved?

I'm sure it can be done but is it hard?

I have an extra climate control box form a 1994 Roadmaster sitting around and wondered if it could be swapped into my 1995 Caprice Wagon. I know they are easy to swap into the Fleetwoods but I dont know about the Caprice. I don't really care for the lack luster Caprice nobs...

Thanks!

I'm in the middle of this job on my Caprice. I went and swapped out the whole box with the blower etc in it. Mine was damaged so I figured this is a good a time as any to make the switch. If you don't mind wiring stuff this isn't all that bad. It's a big help to get the harness out of the donor car.

I am very surprised at the complications involved in this! I was hoping for a plug and play like the roadie to fleetwood swap...
