I'm trying to understand this filter setup. In the photo at the head of the discussion is the filter upside down (in other words, is the clampdown cover normally at the top of the filter)?
If correct, it appears that the two filter sections each have a threaded section that protrudes from the top that then screws into either the other element's base or the clampdown cover. Is this correct?
If the above is all correct, I'm guessing it was done to avoid having to fish the filter elements out of a canister full of dirty (hot?) oil.
I don't recall seeing such a scew topped filter, but obviously they existed. The parts book for MkI* and MkII* carriers, FUC-03, has an illutration that shows the pair of elements as having part numbers C29SR-18679 (I think for the one further from the clamp down cover) and C29SR-18670 (I think for the one closer to the clamp down cover) and C29SR-18697 (for the pair). There are notes in the book that the individual cartridges are "Not to be demanded, order kit C29SR-18697". (No notes seen to suggest interchanges or alternate part numbers.)
A Google on the part number for the kit only produced 2 results, both from MLU....

I seem to have at least partly answerd my own question. Next question is - does anyone have a kit they can measure and photograph so that others can try to search for filter elements that could be adapted as the originals are either in short supply or unavaialable?
