I have a STOCK 99 sport w/130,000 on it . Wheni get it going above 60 MPH it started to develope a vibration that either seems to be coming from the front end or drive shaft. Any ideas on what this might be? I had tires balanced recently and i still feel it.

Check your u joints. When they wear out and get ready to go completely, they can allow the end of the drive shaft to wobble and cause a vibration.

I have a vibration that gets pretty noticeable at 50mph + and it feels like its coming from the front (drivers side, but that could be because i'm located on the drivers side and it feels like its on my corner) it causes the steering wheel to vibrate over 60mph.

What should I check for and where are the U-joints located in the front? How easy is it to simply tighten them?

Front vibrations have many causes. Here are a few, Bad bearings, tires, warped rotors, worn bushings, shocks, U-joints (5 of them), TREs, ball joints. At 130k most of this will need attention, anyway.
