New LS1 Owners - Newbie Tech - Rear end help

After getting the suspension,brakes,motor mounts, clutch & flywheel all replaced i now find myself with a shot rear end. I just want to get some thoughts on what i should do. I was really thinking about replacing it all and going with 4.10s or 3.90s. I haven't driven my TA more than 4 miles since i got it. I knew when I bought it i had a lot of work to do. Its an M6 with all stock gears and worn out rear end.

Please let me know what you guys think. I am on a budget and really dont plan on doing any track time with this car. It is going to be my weekend toy.

Thanks!

If you can afford it get 9 inch rear. If thats not in the cards you can get used rears for around 300 on here and many other places for these cars. Im not sure how much it costs to rebuild one but i cant imagine it being less than 300.

Sounds like ya have my luck. I just ordered 390 gear for mine and it was 280 from summit for everything minus gear oil.
