How Can I Find Out the GM Number for an Opel Manta part?

hi,





i'm trying to track down a GM parts number for an Opel Manta Berlinetta engine mount but i'm having trouble finding it. how can i find this out?|||The old part will have the number on it.


It should be the GM number.


If not, then you may have to ask GM to tell you who manufactured the part, and email them with their number, so they can tell you the GM equivalent.
