Welcome to the forum,
The dogleg 2002 transmission (235/5) does not have a detachable bellhousing like the 265/5 you are referring to. And my guess is the 265 would be a very tight squeeze in the tunnel of an '02 (especially judging by how tight the space is in my own car with only a small 240 overdrive trans) so chances are it isn't what the OP has in his car.
