LCA identification

Is there a guide somewhere that can be used to Identify LCAs???
I tried to use the number stamped into the side but it isn't a part number and I can't find a list of these "casting" numbers by year and model.

It would be great to be able to ID A body vs B-body and year brackets.

How do you tell them apart if they don't have sway bar tabs?

I ended up with two pair of B-body LCAs with tabs (I think - the tabs are on the top of the LCA at one end) and would like to see them find a new home but I can't figure out what years they fit...
Post a photo and we can probably I.D. them for you.
