7" Headlamps H4 Style

Lesson learned from buying on ebay.
I bought these headlights with the details stating they would fit my 71 Swinger.
They are about 1/4 too small diameter for my chrome trim rings to fit securely.
I tried to trim a small plastic portion on the back of the bucket to see if it would fit more securely, but it wouldn't.
They have small blue light with separate electrical leads(not sure what these are for).
These are the exact lights a purchased and you will be getting the headlamps and H4 bulbs:

I'm sure someone else could make these fit there car or use them on something else.
