These power steering reservoir cans are not NOS for a '69 Big Block Chevy. They are original for a small block.
What has been done with these cans is, they have sawed off the return line on the back of a small block can and brazed the neck to the bottom of can. Then they brazed over the sawed off hole on backside. Now they think instant NOS '69 B/B reservoir.
