I think you have some numbers mixed up, you used the 489 356 Re number twice.
For a 481 079 R93 housing assy (deck skin, pan or what ever you want to call it) you need a 481 082 R2 cast nose piece.
For a 489 353 R3 housing assy you need a 489 356 R3 cast nose piece.
Both of these have brackets for the gage wheels. There is also a version without the gage wheel brackets that uses the same part numbers as the second one listed above (489 353 R3 and 489 356 R3), but don't ask me why since there is a slight difference in the housing (gage wheel brackets), I should think the P/N would be different.
