okay, then if it's like the one I have, its just a standard fiber gasket between the adapter and the block, where the adapter bolts on with the 2 bolts....then the filter screws on, and the O-ring on the filter will seal around everything on the block....its a pretty easy setup...and I'm not used to working on the 4wd trucks, but on my 2wd, it has tons of room for the filter, enough to even run a 7qt pan with side kickouts and not have any problems with space.
also make sure you're getting the 2wd filters (which should be the same as the big block filters IIRC), they're larger in diameter than the 4wd filters that mount on that angled adapter.
