Anyway, I'm going to go with a deeper (31x12x3" vs 28x8x3.5"), but 1/2" narrower core, I have no clearance between bumper & AC cond with the 3.5" core & don't like them rubbing together. A small air gap is always preferable for heat dissipation, I'm sure.
I'll need to cut the valance as shown. I know someone on here did this, I'd like to see the pics again for reference before I hack it up. My intention will likely be to reinforce the fibre panel, or add a cross brace, I dunno.
