Just Googled the old Philips cartridge I mentioned above and they and their replacement styli are readily available on the used/NOS market.
You would want to go with a 401 (or higher) and not the 400/conical version.
There is also a new Philips 501-II listed @ Thakker for $120/US, but I didn't see any spec's listed.

My decks came with a plastic cartridge alignment guide (fitted over the head shell) that actually worked.
