attaced file of fel pro MS98002t.

Where the arrow is the area is completely open on all data picture of gasket.. So is tis the wrong gasket for 1999 S10 Blazer 2 door LS auto 4.3L 4x4 or will it work.

I do not have truck apart yet so???? Which one would you all get. I am confused as hell seaching part numbers. All Data part number 89017866?

Thanks

Edit: I guess it is ok to use the MS98002t. That area where the arrow is will not affect anything. Learning as I go just wanted to make sure.
Picture.. of engine speaks for itself.

Guess I should have stayed in school and finished auto mechanics. Thanks.
