What is the thread for this fitting?
Hey guys -- this fitting comes out of the Quaife Q58 (aka non-hypoid) gearbox in my SR8. It's outer thread dimension is approximately 16.5 mm, and the thread pitch seems to be close to 1.5mm. But I've never heard of a metric thread of 16.5 mm, and there's no corresponding imperial size (it's slightly larger than 5/8").
I'd like to convert this to 6AN, but I'm stumped...
John (@parsonsJ), let me look in my bag parts because I may have one that will work for you. That looks similar to the fitting that is used for an SR3 GDU, which has an AN fitting on one side. I will check tomorrow.

@charleyhradicalsportscarregistry-com Thanks Charley!
Thanks for the help! But I fixed it up myself.
Graeme -- that's what I concluded too -- 3/8" BSPP (last 'P' for parallel), which is 16.6mm and 19 threads per inch.
Confirmed: 3/8" BSPP. Many thanks for all the help!
