I am replacing my a/c heater plenum box. (Hopefully I can find on at a junk yard) I have started the process of removing the dash, but have run into a few snags. Would it be possible to see those pics of the process? And also if you have any ideas on where to get a new plenum box if the junk yard doesn't have one.

Thanks
