I have a 68 with a dana 60 srw rear axle. Rigth now it is geared 4.56 and i would like to swap in 3.54 or something between that and 4.10.
Is this something something I could do myself? Is there a website anywhere that walks you through it? What information do i need to start getting parts?

Is there any way to tell what is inside the pumpkin, if its posi/locked open and what spline it is without taking off the cover?

Is there anyone in the st.paul, MN area that can do this for me more affordably than a shop?

thanks for your advice!
