Picked this up at the auction because no one knew what it was for.

Looked up the part number (5044585) and it turns out it fits most 1964 GM Convertibles like Impala , Super Sport, Acadian, Olds, ??? I though it was interesting that they used brake fluid for these back in the day (at least that's what the GM parts page stated).

It's was so cheap I'm not even sure what to ask for it...don't be shy! I just hate to see this stuff thrown out! New motors cost up to $500 on eBay. 

Maybe use it for a project?

Retractable horns for your rat rod, open a board in your truck bed to access the gas tank, ejector seat for the wife, I could go on and on!
