can the 89 3rd generation standard cab be switched to a extended cab??   if so what has to be done?.

Yes, you gotta fab up your own body mounts. Plenty of people have done it. Try searching here and pirate for swaps like this. Remember, anything can be done.

You will also have to shorten the bed, or build a flatbed.

If you haven't SA'd your '89, and you have an X-cab that is complete, it would be easier to just build the X-cab.  Under most circumstances the longer wheel base is usually a benefit when wheeling.
