Help needed with spacing between engine + tender

Hello folks!

Recently i've downloaded a new train, however the distance between locomotive and tender is a bit... Weird.
As you can see on the image, the arrows are off aswell. I read i needed to change the attachment points a.limfront and a.limback in the mesh file. problem is, this mesh file is nowhere to be found. The only things in the map are .tga (texture files) and .kin files (which i can't seem to open).

Does anyone know how to fix this?

To move or change the attachment points a.limfront and a.limback you need:
"Attachment Maker" , more information: http://online.ts2009.com/mediaWiki/index.php/Trainz_Tools_by_PEV
They can also be moved with IM Editor:

No im file? is there a Trainzmesh file?

I did find a .pm file in the body map. I added attachment points with the Attachment Maker, now have the file attach_mesh.im but simply placing it in (one of) the map(s) doesn't work. That .pm file is also the only ''mesh'' file in there

Edit: Okay you guys rock, i edited the attachment points in the IM Editor and no longer is the tender hugging the locomotive. Thanks!
