7 qt pan that actually "bolts in" a BB A body?

I have a customer who needs an oil pan for a BB A body drag race car. The car is a 1975 Dart so it should have all late model suspension and steering on it. I'm not sure which K frame that he has, I need to find out. The car isn't super fast, maybe 10 or 11 second car. He is making around 650 hp. I think a 7 qt pan would be fine if there is one that actually bolts in and fits.

Last time I built a late model A body with a BB I found that very few oil pans fit. I ended up using a reproduction OEM pan. It worked, but I would've liked to have more capacity.

I actually just bought the milodon one on the left for my 383 Demon project. I've used a moroso 7qt deep sump on a 440 Duster too. No issues.
I'm using a small block 68-72 style k member with Schumacher mounts. This will be my 5th bb a body I'm building.
