A "how to" for the flm emaxx chassis???

The chassis came with a bunch of screws so I'm wondering do some of them replace some of the current screws or are they for the battery straps that are in the chassis bag as well?

I haven't opened the 2 bags yet but was just trying to come up with a game plan in my head.


Other than my first question in this post does everything else just "swap" over to the new chassis with a good fit or are there stock parts that don't fit which are going to require me to purchase addl parts to complete the switchover ?
