Sdkfz 251/9 Panzer Concepts 1/16 Armament Upgrade

Hey all,
I just ordered the armament upgrade for my Sdk.fz 251/9 in 1/16 from Panzer Concepts. From what I can gather from the online info, it appears to be a great transformation. I was wondering, before it arrives, if there are any others out there that has done the same. And if so, perhaps offer any pre-build support/info. Thanks to all and Good Hunting.
