not sure what the "S","E" as well as the "DL" bolts are, but the assembly manual does picture how everything goes together, and there really isn't a lot of difference in the 4 eyed front end .... the 5-9 assembly manual is all for the 55.2, that's when it was published, and it does not give measurements of individual parts because it was a reference for the assembly line that didn't have any 'mismatched' components to work with, just indicates what pieces each assembly line station should have on hand, by GM part numbers
if you get too lost CASO, ask away, someone here can help
