That's very odd, 928sg. The fittings on my Red Witch were same length. Like you, I made them permanent.
Be interesting to see where this thread goes.
Good Luck!

This is what I could find this morning, I see one that has longer threads facing the block, 12 mm of thread vs. 10 on the others.

On second thought I wonder whether the different one is a fitting for the oil cooler at the radiator (?) Can't find a separate part number for those.

Rob, it might be an optical delusion, but the third fitting in from the left has smaller diameter threads on the bottom, as well as no shoulder.

Rob Edwards

No delusion at all, you're quite right. It _is_ a smaller diameter:

Possibly only slightly related - when my rad failed I bought a local aftermarket (oz) ADRAD two cooler unit - readily available, cheaper . It came with adaptors in the cooler ports. When I checked engagement with the hose ends, they fitted pitch wise, but seemed sloppy. Compared to the original adaptors, very sloppy. Seemed to be a diameter issue.Re used the originals, no issues in many years. I suspect there are adaptors and adaptors...

you can measure the fitting the block,
remove the line,
then use a piece of bent wire with an L on the end,
put it into the fitting hook the end of the fitting,
then measure the wire,
then measure the surface from the girdle to the tip of the fitting,
then you have the amount its installed into the girdle
