A few years ago, I modified my '84 Monte to use the single motor track from an early '80s Buick Regal. The Regal had a power track from a split bench seat car, and the seat mounting holes are wider apart that a power seat track from a car with the factory power bucket seats. I made some adapter brackets which allowed me to mount my bucket seat to the split bench seat track, and I used it for several years that way. Then I found a factory 3 motor bucket seat track from an '86 Buick GN, and swapped it into the car. If you're looking for the factory G body 3 motor power bucket seat track, then you need to try to find one from an '86-'88 Buick Regal/GN or Olds Cutlass with the power bucket seat option. Try to make sure that the seat track is in good condition, and that the feet of the track (the parts that bolt to the mounts on the floor) aren't heavily rusted. If possible, try to get the vehicle side of the seat harness, including the connector. As Anubis has pointed out, some early to mid '90s GM cars used a 3 motor track which is similar. The seat track mounting points will be different, but the guts and harness should be the same. I had a power seat track here from a '91 Olds Calais (N body), that was a 3 motor track, and I was able to use some parts from it for some repairs to the G body track that I have. Hope this helps.
