ok what gaskets go between where the manifold connects to the exhuast where them 3 studs connects... is it just a metal gasket or is it a donut and metal gasket... also i want to install a oil pressure guase what size guage will screw into the block? .... my engine is a 22r

 

it should be 2 round donut like gaskets. the best thing is to take an old one with you ,the part store has trouble getting the right ones.

 

you sure its not a flange gaskit .... and no one knows what size oil pressure guage?

 

go to the autozone website and look up exhaust flange gasket for your truck. it will have a picture of the gaskets. a lot of oil pressure gauge kits have adaptors to hook the line to the block.
