Thanks JWall and Bnoon, that helps a lot!
Looks like I´m missing the bracket that goes to the oil pan stud. When the engine was replaced, they left some brackets unattached and some are missing and I´m trying to put everything back the way it came from the factory, since the car is otherwise really original.
Not really trying to restore it rather than make it look like a real survivor car in the engine bay also, inner fenders, firewall and core support are still in nice shape, even the jack instruction and the emissions stickers are still in place.
I do have couple more questions, but first I have to learn how to post pictures, too difficult to explain otherwise

.
Bnoon, I hate to ask, but if you could take a pic of the oil pan bracket, that would be awesome!
Thank you again guys,
Antti
