I must have inadvertently bounced a track b/c there's only one bounced clip and all the other muted clips in that track is gone.  Looks like the audio clips are all there in the audio folder.  Is there a way to bring back the clips and have them position at exactly where they were?

If you haven't saved the file and not done a lot of work on it since the bounce, then CTRL-Z will undo what you don't like. If you saved it and have no backups then probably no.

The original clips are still in your project audio folder, so you can always import them again (sorta painful but an option). Ctrl Z is highly preferred.

Or you can clone the track, Archive the original and H and hide the original. Once you are certain are happy then you can get rid of it. 
 
I had so many crashes lately I automatically create clip/stem bounces.
 

Unfortunately I have saved and quit the project so I guess there's no easy way then.
Just a thought that Sonar does have the start, duration data for a clip (properties) it'd be great (and possible) if those are meta data that get saved or are part of the clip.  oh well.
 

Again, you can look in the Audio folder and may find the original clip still there. Helps to know the file name if there's a lot of audio clips.

Correct. You can identify bounced clips in the audio folder, because they will have "(Bounced)" in the filename. So, if you know the original files you were using by name, you can simply re-import them, even on a totally separate track. This is where having separate audio per project makes it easy to find, but more drive consuming if you make many revisions of your project with different filenames, as I often do.

There was a setting that everyone hated when importing Wav file (import broadcast at their timestamp)
There might be a way to import these clips and have them fall where they are supposed to be if timestamp was enabled.
 
If you want SONAR to import Broadcast Wave files always at their time stamped location, go to Edit > Preferences > File - Audio Data and select the Always Import Broadcast Waves At Their Timestamp check box. Otherwise, set the Now Time and current track to indicate where the audio should be placed.

For the next time turn ON "enabling versioning" of projects. (Preferences).
I set to 999.
So you have a lot of backups - for example - to read the positions of the audioclips, and load them into your current version.

+1 for this.....only I do not have 999 versions.  Usually 4 or 5, but 999 might be the best way to go.  Also if you have autosave enabled there is a chance the last autosaved version will be good.  I say this from having experienced exactly what the OP has done and many other things I grew to regret.
 
Good Luck!
