Unknown front end parts

The only thing that can be said is that they are 68 and up and 67 and older STYLE. Other than part number and measurements the vehicle can not be determined. The styles were used on a lot of cars just the dimensions would change. I think we have by part number determined the one with the bolt is a 68 A body and up to 1972 the centerlines should be the same as the 67 down. the angle and offset is not comparable between the two ( different mount to the K frame)

BUT I have always suspected that the 68 up and 67 down offset would be relatively the same so maybe if you overlaid the two with the left sides (in this photo) as aligned on the studs taper as possible you MIGHT see the casting split lines of both line up?

the 67 style number comes back to this when searching it as a Moog number (with the -C comes back as no results)
