your best bet would be too look at an aftermarket locker website. if they list the same part number for 97-current then the oem should be the same 97-current. Because the axles are a different size im betting the spline count is different as well so i dont think they are interchangable.

I did look and found that they are the same part numbers (detriot true trac did). The reason I originally asked was because I found a 9.75 ford racing posi on ebay. It was for a 05. Its too late to get it, but I wanted to know for later applications. Didn't want to get it and not work. I think I might go with an aftermarket. It sounds like people here like the detriot autolock. Going the other way may be a costly technical error. Thanks for your advice.
