07 Chevy AAM vs 03 Dodge AAM

[roachie]

Will parts interchange between them?

Gramps is wanting a posi in his 03 and I have an 07 chevy axle with posi sitting.....

[SKYNYRD]

measure the axle and swap the entire thing be easier if they are the same width.

I think the problem you would run into is the speed sensor in the dodge. Not sure if the tone ring will fit on the gm carrier. Everything else looks really close to the same.
