Found a leak in intake boot

I followed the suggestion about tracking down a vacuum leak and BINGO!! Both of the boots on either side of MAF sensor were dry rotted on the back sides out of sight. The rear one has a branch off to the idle control valve, that one had a huge hole in it that I could fit my index finger in. Getting that one off looks like a bitch, it has a hose clamp holding it on which is buried under the throttle body. Is there a DIY on this??
Thanks for the tips!!
