I must disagree. I had a brand new, beautiful handle for an A Body in my hands at one of the Flings in Van Nuys. I gave the seller a $20 bill so that I could take it to my car to compare. It was a quarter inch shorter than the handle on my car. I did not buy it/them.
....not all the same.
I recently purchased some B body handles. They mount differently than the Chrysler handles.
The B body has more of vertical mount than the C body, as you can see in the pic. (the C body handle is the one still on the door)
