I have a six pac air filter assembly (top ,bottom and oval element) and was wondering if the lid is the same as a 69 road runner air grabber 4bbl air filter lid. I like the look of the big oval air filter and want to put it on my challenger with a T/A hood. it is a single 4 bbl. im not sure that the stud holes in the six pac lid are in the same place as the air grabber lid, this way I can just get the single 4 base and use the top and filter. thanks
