OK, Probably a dumb question, but what are the suggestions on mounting a truck body to a K1E GN (06)?

Do you remove the rear shock tower braces that go to the loop?
Do you lower the loop and the braces?
Do you just cut where you need to to get the body to mold around the frame parts?

Thanks for any help out there.

you are allowed to cut the body to fit over the loop.

You can cut the body to fit, just not for a performance gain.
