I ordered a specific part number which they had in stock. They sent me these as a mistake. They are sending me the part number that was initially requested.
I have a picture of both types of gaskets and you do appear to be correct. It looks like the hole patterns could be the same except one has twice as many holes. I would not feel comfortable about all of those unused holes not leaking though.
I was given the part number from fellow Moparts members and I want to use what they say is the best gasket. The two gasket sets are made of different material and when the next set comes in, I will confirm the hole patterns.

I was told that the original part that I ordered may no longer be in production. Maybe this black set of gaskets is the easiest MP replacement.
I have attached the original 5 bolt grey gaskets that I ordered for reference.

Thanks
