Sounds like Taurus' model 66. The Taurus 66 was made in 6-round versions early in its lifetime and later in 7-round versions.
But to be sure go to Taurus' website and click on the "Find my model" link at bottom of any page. Enter your serial number and you will get model info unless it was made prior to 1985 (I think that's the year?!?).
Hope this helps, and welcome to the friendliest firearm site on the internet!
Update: If its a model 66 you will have no problem finding grips at your LGS, eBay, Gunbroker.com, etc.
