The thick ring gear is usually about $10 more than the standard. The cost of a new carrier is about $50. You can see it would be cheaper to use the thick gear rather than get a new carrier.
The only thing to keep in mind is that if you EVER want to change the rear differential, you'll need to get it for the 3.07-3.73 gear ratio.
