Hi Alan,
Well there's a few choices. Hunt down a 465kc IF output transformer, try Play Things of the Past. Back in the day there where companies that make replacement IF transformers. Or If you have a slug tuned 455kc can you can use it but you'll need to open it up and change the value of the internal tuning caps to get it to resonate at 465kc. Or you could use a rf choke in place of the secondary coil and a small cap connected to the plate of the IF amp tube to coule the signal over to the diode plate. This will make the if rather broad and will loose some gain.
Some of the older Philcos have 460kc if cans you maybe able the get one to go up to 465

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
