Gas Cap

It had a mid 70s cap on it. With the extra prongs. Original cap is long gone. But that cap would sit parallel at least. Whether somethimg got changed, im not 100% sure. Car was restored in the early 90s with some part s from other darts.
Here's what I have. A 4 screw neck on my 70 and a 3 screw on my 66. Both caps are clocked the same but there is a dept difference of the tabs.
