need insight to a-bodies

My name is Brian Buckley I am the sales manager for unisteer performance. We have used this sight for some time now when it comes to identifing the classic mopars we have had come through our shop for rack and pinion kits. We have found it really assists us tremedously, and for this I thank you.

For those of you who don't know we do the rack and pinion kits for B & E Bodies. Finally our attention has turned to the beloved A-Bodies. Now I need some help with A-Bodies. I have been doing some research on A-Bodies trying to figure out the years they span, the different makes and models, k-member changes, columns and so on....

It seems to be getting quite confusing. Appears early model A-Bodies were large cars not the small compact go fast cars I thought they all where. Someone tryed to tell me that all A-Bodies turned to E-Bodies after 1970. I know this is wrong because I have a '73 Duster in the shop now. I believe this is true for the cuda line, but that's about it.

Feels like I am losing my mind trying to figure these cars out. I know you guys (and ladies) have the knowledge, please help down the path of clarity.
