this is a 1970 Chevelle, Nova and possibly others. It is the flat bottom washer bottle #3961557 with cap (short rib) and hose screen. It has some slight yellowing due to being almost 50 years old. No cracks!, cap is tight on it. Very nice original.
$80 shipped in the us (others slightly more)
Paypal F&F preferred
Thanks SYC!
