I was able to get an OAK kit for my Harman Accentra insert so I installed it along with a block off plate this past week. Needless to say, my measurements weren't too bad with the exception of the holes for the exhaust and intake flex pipe. I used 4" pipe for the intake. Thank goodness for furnace cement to cover my mistakes ![Smile :) :)](/talk/styles/default/xenforo/smileys/grin.gif)
