67/68/69 cuda dilemma

And as it stands right now with them discontinuing the fire walls and plenum from AMD I'm gonna have to look at this pretty hard tonight and see how much of a ***** is to change these 2 parts. Because I may just be installing a brand new fire wall and a brand new plenum, Since I reached up in there after taking the air box out and the heater out and it's really crunchy in there. The original Plan was to remove the upper cowl and clean everything out in there. Treat for corrosion, and epoxy primer and paint.
