I checked an old parts Lookup CD for C5's that I have and the part number I found for a '99 without AH was 09367071. GM was always superceding the part numbers. I did some checking online and the part number shown in your picture is also shown on the part shown here as an example of a '99 EBTCM without AH. http://www.automotivemodules.com/Corvette-ABS.html
The M for non-AH or the V for AH should be on the same label as the part number, as shown in the link I provided.
I would think that a GM dealership should be able to search for all the part numbers that superceded the original part number for a '99.
Here is a picture of the label from my '99 with active handling. Hidden from view by the radiator hose is the large V identifying it as an AH EBTCM.
My Parts CD listed the EBTCM with AH as part number 09376711 and as you can see in the picture the part number for mine has also changed.
