Direct Connection Air Cleaner

Want to buy a 70’s era correct air cleaner.

I’m just about done with a nearly stock numbers matching 1973 340/4-speed Duster ( Arthur’s Duster ). The only contemporary things on it are an aluminum radiator and MSD distributor.
The only other upgrades I want to do on it are Day 2 upgrades. I scored some vintage DC valve covers and have an LD340 that will eventually go on it. Would like to get an air cleaner like this
