Whats up, sorry I did not catch this earlier I spend my days in the 2000-06 section, just by looking at the photo the trim sponge should be outside of the box not the inside fixing that will leave you plenty of room to clamp the filter on, As for the hole in the fender, the wheel well holes are oversized when you mount the box just hand tighten the bolts and adjust the box then go back and tighten them, As for the throttle body gasket it is a direct stamp of the carb make sure you do not have it upside down 90% of the time this is the problem, you do not use the OEM gasket, Does your stud have a 45 degree bend or a 90 it should be a 45 give me a call I wont be in tell tuesday so here is my cell 909 809 8242 thanks Daniel ps pm me your address so I can send you another filter that one looks a little worn out the filters crush like that when they are not serviced correctly
