quick leaf spring question.

I have a set of springs that have a different spring eye on one side. It's a smaller diameter. Can anyone tell me what application that may be? The guy that gave them to me said they were for his 66. I'm at a loss on what they fit. Figured Id ask on this thread since it related to springs
if it's the front (shorter section of the spring to the locating pin) then they ARE for early A's (63-66 for sure). when I ordered mine I forgot to state that they were early A's springs and they came with the larger style bushings.I had to drill out my bracket and get a larger bolt.
