Rocker panel replacement ?

[71c10longbed]

I am in the process of replacing inner/outer rocker panel, bottom of a-pillars, and cab supports.

I am using the inner rocker replacement panel that includes the outer portion of the floor pan.

I have everything cut out and tacked/screwed in. The door fits fairly well.

My issue is that there is channel or ridge created between the inner and outer rocker right around the weatherstrip area. It should be about 1/2 inch wide. My is about 1/8 off towards the back of the truck. It doesn't affect the outer rocker fit because I can adjust it. I will try to post some pictures later.

My question is - does this matter or will it be covered. If it does matter I need to trim the floor pan an extra 1/8 inch in the back - which means unscrewing/untacking etc...
