3.90s in a stock 10 bolt..how do ya like them?

and will they fit? I see the 3.90s have a 43 tooth ring and I would think that may be really close to the housing. The 41 tooth is already pretty close. If they do work do they seem to be a quiet gear? I have set up several sets of 3.73s and they were all quiet.

3.90's in my old 10 bolt. Pretty disapointed. Thats why I went to 4.30's in my 9" so glad I did.

I have 3.90's in my A4. I'm pretty happy, but I don't any comparison points except an old Monte Carlo I once put 4.10's in. I haven't been to the track yet with them, but in driving around it sure is tough to keep good traction when launching.

They have a little extra noise over stock, but seems to only be at 60 mph though.
