CCU removal procedure 300sd 83

[300sdToronto]

OK, tell me it ain't so .... I need to remove the climate control unit for repair in my 126 chassis '83 300sd

If I had a 300d it looks like the wood trim panel around the CCU just snaps off BUT, 'cause I have a 300sd, I found a posting that says I have to remove the radio, then remove two screws on the bottom of the wood trim before it'll pop off.

Is this correct

Start at the ashtray and work up. It's really not bad about 6 screws and 4 wire connections before you get there. Then 2 small side-mounted bolts and 2 connections on the back. (Be careful of the lighting attached to it.)
