Do you know where I can get a good set of 3.73 gears with install kit online. For cheap?

One more question for you. I already have the performance 3.42 axle in my trans am and am thinking of going 3.73. It is my daily driver would you recommend the 3.73 gears or 3.90 gears? Do they even make 3.90 gears?

How do you have a 3:42 axel in an auto? A4s with the performance axel got 3:23s. If you have an A4 I say 3:73s.
