M1 intake and serpentine accessories

Thank you Bob, for taking the time to point out these differences to a Mopar Newbie like me!!
FWIW I am planning a 5.9 in a 87 dakota 4wd 5speed. So far, I have swapped the 6cyl nv2500 trans for a nv3500. I am finishing up a 8.8 disc brake rear install....
I have installed a carter 4070 external electric fuel pump so I will not need a mech. pump....
I really need to keep the serpentine drive. It is a little shorter then the v-belt drive, and its space I just dont have in the dakota...
Again, thanks for your help.
