Need help, Changing my diff...

Hello everyone...
I plan in the next few weeks changing my rear end unit, Taking out my 3.15 unit and installing a 3.42 unit.
Does anyone know of a write-up on this, I have done a lot of work on cars in the past, But I have never worked on the Vette to this extent, I am sure it is something I can do, But would like some pointers..
Thanks in advance.

This may help you ... it also has some embedded links to other articles.

Good luck! I'm thinking about doing this mod too!

3:15 to 3:42...

If you're changing for a performance boost, you'll never feel the difference.

I agree. I recently changed my Z's 3:42 to a 3:90, and didn't make that much of a seat of the pants difference. If I would have jumped up to say 4:10, I'm sure I would have been able to feel the difference. Just from looking up previous posts, in regards to diff. change outs, I was able to do my own work, by myself. Good luck.
