i too thought it was a silly contraption being the inside dimensions of the bellows is smaller than the IC itself. i made an cardboard cover for the one in the red car. just slipped over the IC when i needed it, and when i needed a little extra balls, i would pull it out and cram a bag of ice in between the IC and the condensor, then ice the blower, and make a run or 2. you can make the template with cardboard, then find a metal shop in your area. they copied my template to DIAMOND PLATE (thats all they had at the time) for 20 bucks. i still have that thing around here somewhere unless i gave it to mike puckett with my old red car
