MK2 Carrier oil filter elements?

[rob love]

I am working on a Lynx, but the filter housing on the mk2 carrier is actually a Lynx item, as evidenced by the part numbers prefix (C29SR). A search on MLU revealed the commercial part numbers were Kralinator K505 and K507 (two separate filters that join together). I have tried searching for them on the internet, as well as trying cross references on some of the other manufacturer's websites (Wix and Baldwin) but to no avail.

What are you guys using for the mk2 oil filter cannisters?
