chevy 8.2" 10 bolt with 8.5" Posi

[tgvettes]

I read somewhere that you could do this. Does anyone on here know if this is true. The only reason for me to do it is that I want to use a Detroit true track posi which is not made for the 8.2. If this can be done is there any machining needed or is it a bolt in. Do you use the 8,2 gears or 8.5?

I appreciate any answers. By the way I have about 450-475 horse LS motor and 4L65E going in the car so don't tell me to buy a 9 inch or a 12 bolt I just don't need that.
