Ok....since I am still in Canada and not home, I can only give you the following suggestion...similar to what I went through.
Measure the OD of the air filter you have. (I assume its 14" or near)
Measure the ID of the filter so you know the thickness.
Measure the height so you know what can be used or whats close.
With these in hand and your tape/ruler, get to the local Autozone, Carquest or whatever and start checking. (Yeah I know its a bummer)
I did also send an email to the tech departments at Fram and K&N with the same info...K&N had one that was very close in OD and ID but was still too tall and way too expensive.
