Sometime ago a nice chap posted the following photos on missing-lynx forum taken in Kabul.
Since I have a 1/72 ACE BMP1 & ZU-23-2 AA kits with me at the moment, I am planning to modify my BMP1 to depict that one shown in the picture below.

Since there is no pictures showing how the AA gun was mounted on the vehicle, so just wonder any of you out there can give me some suggestions how to go about this project.
Please bear in mind that even though I been modelling for >5 years (++) , but so far I am only following the instructions. This will be the first time I try something like this.
I am not in for accurate depiction, just something look convicing enough in 1/72 scale will do me.
thanks.
