inner rocker outer floor

[Swims350]

I'm a lil confused on these parts anyone shed any light?

My 83 is going to need the inner rockers changed, and cab floor pans as well as maybe the floor support but anyways, looking thru pieces this outer floor piece confuses me isn't it the same as the inner rocker?

then for floors I was going to get these, and not the ones that have the drop off on the sides which looks to me like it's part of the inner rockers or other panels I need, and these cover more, I've got some spots near the tunnel

Kinda looks like it to me. Redundant parts that is.

my thoughts exactly I was thinking there isn't like 3 to 4 layers there. maybe in front at the kick panel but not along the sides, I was thinking just floor and inner rocker then outer. not like outer floor with a piece going straight down, then the inner rocker on top of it going straight down too, then outer attaches to those. I'm sure I'll know more about it when I start cutting into mine, I hope to tear it all apart sometime soon before winter sits in
