Big Car Air Cleaner top in great condition

Hey all, looking for one of these, but in much better shape.

 

Can you get a measurement, I have 30 year collection that I just pulled out. Joe

 

Here is what I had that size, not sure so I took a low view so you can see if it dips in the middle like this one does. If it works, its $40.00 shipped, sure half of that is going to the USPS. (LOL) Joe

 

Thanks guys, I'll have a look at my own and decide. I may just run it flipped over and ignore running it correctly

 

I could blast that and make it look like new.
