Default 3:42s Help please....

I have been trying to get a price on some 3:42s and the guy at Advance is telling me all I need for an upgrade from 3:15s is the ring and pinion and I can use all the other same gears. So I go to Summitt racing and there price for the ring and pinion is like $175.00 something about this just doesn't sound right. Other folks on ebay and such are selling the whole deal for like $1000.00, but are calling it a differential, what am I missing? I am going to have BlownZ06 do my work for me and he recommended maybe trying to find some used ones, to save me a few dollars,so this is what I'm doing, only I'm having trouble figuring out what part to ask for....tom

It depends on wether you are going to build the carrier or buy a complete rear diff. If you are going to build it yourself then you can go with just the gears, which btw I have a set of used 3.42's out of my coupe I will sell for $150 if your interested. A new complete 3.42 is around $1,100 from GM.
