Honestly, I haven't really decided but I'm leaning toward something along the lines of Vintage Air. I've read in more than one place that they are more efficient (work better) than what came factory. I like the idea of getting rid of that huge heater core enclosure in the engine compartment also. In any case I was not having much success trying to get a flat surface with all my welded in patches so figure worse case after I patch that area flat is to just re-cut the holes if I change my mind back toward factory. There wasn't really much of the system left when I got my truck so most would have to be bought anyway for a factory setup.

Any particular reason you are going with the Blazer system? Just get a deal on a whole setup or do you like it for other reasons?
