Radiator is AC Delco 21033 or Spectra CU 1693. The Delco is thinner than OEM.
Lower shroud is GM3110117
Upper shroud is GM3110126

Ya for some reason some of the 305s got the smaller radiator that was 28" wide while some had the 34" like a 350. Looking at RockAuto's site I am guessing trucks with the 100 amp alternator got the smaller radiator.

My 88 - 350 came with a 28" wide core and 34" overall dimensions, make sure you're comparing apples to apples.

Sure, my 94 350 Tbi is the same way. I am talking about the 96+ trucks, and really just guessing based on RockAutos info.
