if your set up is like my 1990 nbs style, you basically remove all that crap and throw it in the garbage then you have to buy a adapter that screws onto the block

if you order that adapter it does not come with a gasket. which i found strange but i guess if a bit of oil leaks its not going anywhere
when i did my 93 s10 it was just a double sided threaded piece
