Chances are the air cleaners that YOU have are the ones that IPSCO made for just about every Pantera shop out there?

Try their web site first. Then call them if you have too.
For some inexplicable reason you have the wrong air filters on the right "air cleaners".
The tops and the bottoms that you have were made in consideration of what air filters were available. Not some Phantom that never did exist. There is an K&N filter they were made for. You just ain't got it and I just don't know the part number.
If you are interested, there is probably another 80 t0 100 hp that is hiding in that engine if you run the stacks naked?
The air cleaner assemblies really offer no special advantages. In fact they are cumbersome as all heck. They even partially block your rear view and the only thing they are even marginally good for is keeping the water out of the stacks when you wash the car.
Call IPSCO. Describe the air cleaners you have or even text or email them pictures of the tops and bottoms that you have.
They very likely will say, "yep, we made 'em". Then there is your window of opportunity, just say, "I need new air filters for them that fit right", well considering all the aspects of recent discussions here, maybe say "I need the correct air filters". Stay away from using the term right.
They might misinterpret that to mean you don't need the left side air filter too?
Hall probably has the filters separately also?
