Removing the clock means removing the instrument cluster, which can be a bitch of a job. There's a large plastic nut on the back of the cluster to hold the whole thing in place. I was doing a blower motor replacement job and had to take out the dash to get to it, and I thus had easy access to that nut. You will need to remove some of the access panels to get to the back of the cluster.
You will also have to unscrew the speedo cable. Do so gently.
The clock itself will then be easy to access. Just be aware that few of those things still work, but there are outfits that repair them. Do a general search in this forum to find some of the vendors.
With the cluster out, I'd suggest replacing all the bulbs, whether or not they work. Also, if you think there might be any kind of problem with the speedo, think about getting it overhauled or rebuilt. I paid about $140 to have mine rebuilt (it was DOA anyhow).
As for the radio ... I'm not sure. I replaced mine with a new JVC system...
