3.90 gear with stock rearend

I have the stock 3.42 gear. I am thinking about putting a 3.90 gear in soon. Who makes a 3.90 for a stock 1997 rear? I want a good push from a stop but something good for the highway also.

Occasionally people mention 3.90s, but noones ever been able to tell me where to get them. ;) I think your SOL, but if you do find a source for 3.90s, let me know too. Sorry I don't have better news for you.
