I tried to search this on the forum, but no luck. I'm building Meng's King Tiger and they fail to mention which vents (?) go on which version. So, for a King Tiger in the Ardennes, which parts should I use?

In this case, I think I should use both A14.

Here, I'm pretty sure it's part F52.
Finally

I think part I should use B17, but I'm not really sure.
Any input will be appreciated.
Thanks in advance,
Ricardo
