Hi everyone!

I have been sorting out odds and ends before I throw things away.

Found an interesting cap that at first I had thought it was off of a newer car.

I do know that in 71 there was a screw on cap but never saw one or realy looked at one.

Need to know if my cap is a real 71 coolent / wiper bottle type.

I gave some hints, since I would prefer to have someone who realy knows, explain what it should look like first.

Note: The cap I got does screw down on 71 bottles ( I know because I have both a vacuum and electric pump types) and snaps on 72 on up bottles but not very tight. All the other caps I see are a flip top with a bleed pin on top.

Dude
