Need Help ID ing these Sway Bars

[Rat Rod Al]

I have 2 sway bars. They are the same. 15/16" dia. Are they for A, B or E body?

As the pics show. 44 1/2" center of eyes.
And with a straight edge across the rear of bar to the front edge of bar is 15 1/2:

May as well ID these to, while we're at it !
Left one is a little thicker than the right one . Anyone know what these are for ?
Thanks for any info !

Bars are B body, middle of the year 66 through 69
E body bars don’t look like that.
