My 72 108 radio (Becker Mexico which I swapped in for the original Europa)pulls out the front. The radio trim plate has two tension springs at either end which can be released by pressing them with a small flat-edge screwdriver. The notches for this are very discrete and run parallel with the wood dash. Once the plate is off (knobs off first -- some press on, others have a tiny set screw) you will see how the two up and down bars are held in by the screw in the middle. Easy removal, of course assuming you have some type of Becker radio.

Good to have another 108 appreciater here.
