Hello, Question about the alarm sirens on 996s. The siren in my 2004 car is part number 996.618.237.03. I want to get a replacement siren, but the part numbers that I am finding are 996.618.237.01. Both appear to have the same casings. So, I need to establish if part number .03 is the same as part number .01. Any ideas please? Thank you, Peter
