a10 alternator crank

[EDDIE SIMPSON]

hi, a long shot i guess. but as a hoarder myself i know there must be others here.
i have some post 60 alternator crankcases. i have a small journal alt crank but would like to use a large journal one if they exist. even a photo of the crank would be interesting. d/s spline will be smaller than a10 or a65 on the originals.
