Cat Filter question

What is the Caterpillar filter replacement part number for the conversion kit that came with the Lubrication Specialties set-up? I emailed them but never got a response and I don't want to pull mine out until I have the replacement in hand.
Thanks.

Thank you! That solves my problem.

Nictane does sell the adapter for other filters, call him up, i did so i could use a larger cheaper filter
