I would say that is the 66 and up pan based on the measurements I have the 66 and up pan the drag link hole is usually centered on the second pan bolt from the back - its definitely old as the new ones use a square opening for more drag link room - Because Charlies went out of business in the middle of my build - I went with the Milodon 31420 - its only 4" off the ground and if i drove it on the street it would be an oil spill waiting to happen - next time the engine comes out I am changing pans to a custom build
The 31420 is for the early chassis, 31470 is for the later. I do street drive mine still, so this really isn't the pan I wanted, but figured I can modify it. I'd love to have one of the Charlie's pans since they are shallower. Sucks they went out of business.
