Spin-on Oil Filter for a 292 Y-block

[tsanborn]

First let me state categorically that I'm an idiot I finally got around to changing my oil today on our '56 Country Sedan with a 292 Y-block. That's not the stupid part. I removed the oil filter and handed it to my local O'Reily sales person, who handed me back something that looked similar, right exterior dimensions and (here's the part stupid part) I let them toss my old one. I got home and tried spinning it on after removing the old rubber seal and putting a bead of lubricant on the new one. To my surprise, I found that the female treaded part of the filter was just a bit larger than the threaded male part. Crap! Went back to O'Reilly to recover my old one so I'd know what the right size thread needed to be in a new canister. Yup, trash had already been taken out and thrown in the dumpster. Did a little dumpster diving but it was a horror show of oily parts and broken glass and finally gave up. Now I have to shamefacedly ask the Forum if anyone knows what filter I need to order for a 292 Y-block. To be clear, the outside diameter of my old filter was the same as the one I bought. Only the interior threaded part of the filter was just a bit too large to fit the shaft attached to the engine side of the fitting. Any help would be greatly appreciated. And note to self, don't throw old parts away until you're sure the new ones fit!
