Boatpuller, I have just ordered everthing(I think) that I need to update my blazer ac to vintage air. I went with the new genIV magnum and the new 3 knob control panel, and the necessary hardware. What tips can you give me about the install? I am thinking of running the hoses through the hole where the blower motor hole is. I dont have the parts yet, but I cant wait to start pulling everything apart.Any help would be great, btw the blazer is a 79 with a zz4 crate and gm serpentine belt setup. side note I see your from WA, I grew up on the east side (spokane). I sure dont miss the weather, gotta love arizona in the winter,gonna be in the eighties this weekend. AZ summer=Magnum AC
. thanks jesse
