I just saw this one on Ebay, nothing to do with me so check before you buy.
I think... ( i need to check ), i have a couple left over i had cast and broached, from restoration projects.
You can check them out here, along with other correct period original restoration parts. I believe i may
also have some of the ancillary parts, like clutch stop etc. These have not broken in serious usage.
Perhaps best to contact me through my website.
