I checked the axle late last night (early this morning at 2 a.m.) because I couldn't wait. Arowhed and Mike Nixon both are right, the axles are the exact same length. There is one very important difference though... the 65 is a posi unit!
That's probably what I bought it for, although I would love for it to be shorter because now my wheels won't fit right!
I guess I am going to have to go back the drawing board and find some wheels that measure up!
Thanks for the help to both of you and I will post pics when I can figure out what to do next...
