200BX Mod Help

Hey, So I tried my hand at modeling today and I'm having a little issue. I started with a 'coupe_body.dae' and did some redesigning. Changed over the bodies inside the dae file and exported in blender. Problem is, when I load the car in game the body is still the same and not updated. I'm by no means an expert at this stuff and any insight would be greatly helpful.

Here's what I'm trying to do.


The Model as saved in the dae file. (I did remove some body pieces so it can be seen better.)


And here's the same file in game.


Any input would be greatly appreciated. I was using the D-trox mod as a template if it makes any difference.
I've attached my dae file if anyone wants to check it out and tell me where I messed up.

 

I don't know for sure, but it's probably something to do with the flexbodies in the jbeam. Unfortunately I can't really help you much further, but at least it may point you in the right direction.
