Harman P38 OAK question

[m159267]

I have owned my P38 for 6 years and have used the Harman recommended OAK for all that time.
1-10-08542 cover & 2-00-08543 - 2 3/8" flex pipe.
OAK works great but looks bad where it goes through the drywall to the outside - there is no inside cover plate. It is just a hole in the wall with foam insulation around the flex pipe. It also seems silly that the flex pipe fits loosely inside the air inlet extension on the back of the stove.
Has anyone setup their Harman with a better looking/more efficient OAK?

I don't have a Harman but I just installed OAK for my stove over the weekend. You can check out pictures of the install here:

You can trying looking in Lowes/Hardware store or even on line for an inside cover plate.

If the air intake on the P38 is the same as the P61 / P68, and I suspect it is, there is some info in this thread that talks about an alternate method to using Harman's parts, and so far the folks that have used this technique seem very pleased.
