Stanton 500e MKII Cartyridge??

Here's a wierd one - I have a Stanton 500e MKII cartridge that was OEM with my Thorens TD180 tt. No problem getting 78 rpm stylii, but no one seems to know what the original stylus replacement is (should be something like a 1 mil for 33's, I think. I know the 3.0 mil I use for 78's isn't so good on vinyl). Anyone out there know what I should order from whom? Have tried J and R (sold me the turntable, but no help on this), Garage-a-Records (no listed stylus other than 78s) and the Stanton website (no listed replacement). What to do what to do....?
