Are we talking 383 or 440, or does it make a difference? My brother owns a '70 383 auto R/T Challenger with a 22" rad, it has a shroud but I do not see where it appears anywhere on the buildsheet. The fan is listed as 24 and the fan spacer as 10. I agree with KissAlien that the part number for the shroud would be 2998328 and there is no column for shroud and also no '28' anywhere else on the sheet.
