Looking for an OEM 70 starter for a 440 car

[7E-Bodies]

Hi all,

As my 440 nears completion at the machine shop, they've tipped me off that I have 4-6 weeks before they run it on the test stand and perform break in and dyno. They've requested that if I'm getting my starter refurbished I'd better get on it as they'll need it. The current one I have is a typical NAPA exchange from who knows when. It's coded for 1973 but appears to look like the original from a few feet away. Before I drop this by our local rebuild shop, does anyone have a core pre dating 11/4/69? Here's a pic of the 73 one that was on it.
