I went ahead and bought the exact same A2A IC that epix purchased and threw it in the truck (31" x 12" x 3"). I wanted to keep the A/C at least for now (AZ summer's right around the corner), so I had to modify the core support and grille fascia pretty extensively to fit it up front. It's a bit unsettling to cut up the truck with fresh paint on it, but I think it'll be worth it in the long run...
