Rick - you got the truck and parts in front of ya, only you can see if it'll work similar to the pics I posted!! I can't see what you have to suggest what might be missing or which direction anythig fits
need something to mount one ear of the alt to the manifold, and if you hang the alt up by the top adjusting [slotted] bracket, you should be able to hold bits and pieces between the bottom of it and the manifold and see what's what
