It might be 33-2232, but check it out for yourself at K&N's site. They have an online application guide.

It was definitely a tight fit for me too... I ended up taking the air box out. With the box out, it was a snap to put the K&N filter in (part no 33-2232).
Here are some useful instructions on taking out the airbox - there is not much difference between old age and new age...

Do you have to put oil on the k&n filter or something like that? I remember reading that somewhere.

That's correct. K&N has their own special oil for their filters. I think I used to use the one in the spray can. Follow their simple directions and don't oversaturate the filtering medium. The K&N oil is a part of the filtering action.

you only need the oil when you reuse it.

I also forgot to add that at that time it needs to be cleaned with K&N's filter wash (solvent). This is the most time consuming part and messy of the re-use. Hitting the filter against the floor or blowing it out with compressed air doesn't work too well because the dirt really sticks to the filter material and oil.

don't take out the airbox, waste of time (those bolts on the bottom are PIA to loosen). just make sure to wedge the top back under the tabs so it fits tightly.

Im just curious is it just K&N or are all the aftermarket drop in's thicker than stock?
