I've seen smaller filters handle more pressure than these old beasts make, I doubt it will be an issue. Add on the surface area of a elemnt that large, the average PSI on the element itself is relatively low. So long as the element has the perforated metal outer casing and your pressure is coming from the inside out it should be fine. In the case of the canister like I have that would mean reversing the flow so it comes in the bottom and out the top/side.
An issue that comes to mind is wether the canister lid seal can handle full pressure w/o blowing out. Once warm the oil pressures aren't so bad, but those cold startups can be fun. I've done pressure/volume conversions on smaller engines that were known to blow spin-on filters apart on a cold morning. NOT fun,...
Realisticly, you could go to a commercial truck shop/parts house and talk to them about finding a similar looking modern unit that takes modern reusable metal mesh elements and adapting it to fit your mount. A coat of paint and a re-pop Fram decal kit and you'd be set!

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P
