Ok, I cleaned this up a little.
OP, I don't know the answer, but you say you have an invoice. Do you have the source of that invoice? Is it a shop or a parts importer? I would think that that would have the info to get you a phone number and call and ask.
There are some pieces of info here. You might not know without pulling the engine apart and looking at the block.....which would be ridiculous to do.
Do some research. Are there different casting marks? Hints pulling the oil pan? I don't know.....
