Have someone shift the car in drive and reverse, step on the gas etc. with the front wheels up on jackstands.  Watch the engine and look at the mounts to find if they are bad.  Could also be a harmonc damper.

i've replaced the upper and lower right side mounts and reinforced them with poly but noticed that the tranny mount is still pretty bad, lots of back-forth movement right at that mount (its on the drivers side bolted to the side of the frame). I'm going to replace it soon, as well as the CVs (which are clicking) and pray that several years of driving the car with bad mounts hasn't ruined the balancer as well.

don't know if it will help or not, But I once had a 1990 Dodge Shadow that had a bad CV on the passenger side and it would click pretty bad around a turn and upon giving it a decent amount of gas it would vibrate like a mofo. After I fixed that axle vibrations/ clicking gone.

Definately replace that CV.  If left it could fail entirely and cause a bad accident.  I take a scrap piece of metal and bend it to fit over the boots when working on the font end so I don't mess up a good boot.  Even cardboard could help there as the split replacement boots are almost all worthless and the solid boots are a real pain to replace.  While at it check the lower ball joint for wear, it really sucks when the wheel tries to come off at speed.

The damper should not be affected by the mounts.  But age can deteriorate it and cause it to fail, give it a good eye when you do the axles.

Thanks for the advice, within the next few weeks: both driveshafts, new control arm assemblies with ball joints and bushings which i bought several months ago, a new tranny mount with poly reinforcement, poly tie rod boots, and a front end alignment. Also, the exhaust needs to be tweaked as the intermediate pipe is bumping against the frame after the cat right before it goes over the rear axle. I'll need to realign the whole system from the front pipe connection and tweak that hanger on the rear pipe before the muffler, and the muffler sounds loose and poppy inside as well, probably replace it as well.
For scberetta3800, take docrodg's advice and check out those mounts, do it now before they destroy your whole driveline like they did mine.
