Inner rocker panel question

[67Steven]

I finally tore into the passenger side rocker. Doesn't look to bad, A pillar was solid-ish, but rusty, so I am replacing that.



And obviously the lower kick, inner and outer rockers.



I am using the truck inner, and I have a question regarding the indents on the bottom where it meets the rocker box:



Are the two areas supposed to fit on top of the rocker box? It seems that they are way too low. If I force (and I mean FORCE) the rocker box down to allow the inner to sit flush, it puts a bow in the box. The original inner was rusted out, so I have nothing to measure from or to.

I tested the outer rocker without the inner, and it snaps nice and clean onto the rocker box and lines up nicely.

Should I cut the tabs or slots up to match the rocker box floor? Will I then need to cut the bottom off of the inner rocker?

Thanks!
