It might seem an overkill, but... you can use the parts that cover the second seat of the mastercraft kit in the Arma Hobby kit. A bit of kit bashing. And the decals. Moreover I can send you my leftover decals from my BR turned Team Iskry kit.

Thanks for the offer Maciej. I think I'll combine both kits somehow, but let me finish Iryda first 🙂
