I think this overflow fits a 75-76 (possibly newer) Plymouth, Dodge and Chrysler. I don't have a parts manual for those years, so I'm going by other ones listed on eBay etc. Feel free to correct or inform me otherwise. Anyway.... It's in used condition, no cracks, but a little dirty. The top is there, but has had a zip-tie repair. It's great for a driver and when I acquired it, it was bolted to my '70 300. EDIT: Pay the shipping cost and you can have it. PayPal accepted. Message me here.
The '72 is part# 3574151 I can't find a decent picture of one that I can verify as the correct one. The good news is they used that bottle across the line in 1972, the bad news is it's just one year.
I just was looking at the one I pulled from a '78 Magnum and this looks just like it. May be a Late B-Body part as well.
