I know this info is here, but some of the post were not overly clear. I was going to install my new Blue Spring Kit and found my pile of crap plastic CAC tube had two small holes in it. So I ordered the new parts from Tousley

. The part numbers you need to do this are:
6C3Z*6C640*B - 43.52 - HOT SIDE BOOT
6C3Z*6C640*C - 59.28 - HOT SIDE BOOT
6C3Z*6C640*AA - 105.49 - UPGRADED CAC TUBE WITH BOOTS AND CLAMPS
Sorry I do not remeber which boot goes at the torbo and which goes at the cooler. In my mind if you are replacing one do both. The new CAC arrives with boots and clamps

.
Hope this does somebody good.
