body drop question

whats up guys im going to be doing a sfbd on my yota and i was thinkin of goin to the door or like a half inch from it. my question is do i just cut the rocker completely off or do i do it in sections.

What I would do is pull the body, make your cut and plate it. I wouldn't cut the rocker completely out.

so basically do it in sections?

Like stitch welding, remove a small section & weld up ,than go to the far end.
It will spread open if you grid it all off @ one time!
