78 blazer 2wd rear axle flip

[MIKEYV8]

Hey everyone,

Soon I want to start with a rear axle flip on my '78 blazer 2wd.
Now i have givin it some thought and a few questions come to mind?
-how deep should the c-notch be in the frame?
-and does anyone know what the right pignon angles are and how exactly can i measure this correctly??

does any one maybe have a link to his tread for me with some good pictures and pointers?
I found a few but can't look through all the posts

Thanks Mike.
