1750 GTV Ignition Lock

[Evan Bottcher]

Looking at GTV parts, one item on my list is to replace the ignition lock.  An example picture is attached.  It was deemed unrepairable way back when by a locksmith, I thought it would be reasonable to find a new one.

Looking around the interwebs, I only see a slightly different item for sale.  Example here at ebspares:

Does anyone know a source of the correct style?  Does this one fit inside the column cover?

thanks,
Evan.
