I don't have an Hughes Deep Transmission Pan, but a Art Carr Deep Transmission Pan and I too used a 700-4r filter, with a 200-4r tranny gasket, and no cutting or adding an extension tube. I know it sucks if you buy the kit which comes with a 700-4r filter and a the gasket is fitted for a 700-4r tranny, and not for a 2004-r tranny.
You will need to buy each item separately or individually of the 700-4r filter and 200-4r transmission gasket.
The photo shows the 200-4r filtration is on the top, where as the next tow photos 700-4r filtration is on the bottom. It doesn't matter comparing them side to side, as long as Dave pointed out you will need to grind down the 3 bottom filter pads on the cover by about 1/4" in order for the cover to fit without squishing/compressing the 700-4r filter.
