Pictures needed Differences in trunk pans 70-71 challengers

[cuda hunter]

Can anyone please supply me with the difference's between early and late 1970 challengers as well as the difference from the 71-70 trunk pans? 

Are the interior floors the same across the board or are there differences between the early to late 70's and the later models?

I think the main difference is the shock mounting bolt hole access locations. Pretty sure all else is the same.
