Replacing standard BIS Ak47 model

[Bucket man]

Im sure everybody knows about the great AK-47 Smith made to OFP long time ago. Id like to replace the model and textures of the basic AK-47 in OFP with the beauty that Smith made.
So the question is how do I do that? I assume I must open the config.bin, am I right?
Broblem is I dont have the knowhow to do it, nor how to replace the actual model&textures. So all the help from OFP addon guru's is much appreciated.

After much beardstroking, guru #127 replied:

"If you want to replace only the model and textures for your own use, it would be easier to replace the original model from "Data3d.pbo" and put the textures in a .pbo in your "Addons" folder. You can use one of the .pbo unpacking/packing tools for that.

Modifying the config can be a bit of a headache. And from what  i've heard, in MP, servers can detect a modified config and might not  allow you to join. Cause if everyone would be permitted to tweak their configs, that could lead to cheating. Peace"
