OK boys and girls, reporting in on my intake boot. After many hours the scat hose did not cut the mustard. It was fine except for the mechanical integrity of the bypass hose fitting that goes to the warm up regulator and a sensor. We tried reinforcing it with different types of material but the scat is so light and flexible it would not hold well.
So we ended up taking the boot, matching the rip to each side of the two pieces and using RTV. I was not very hopeful here but my buddy did the squeezing and I held it together. We just did enough to make it hold. Then, 24 hours later applied a second coat only this time it was a heavy amount getting the large hole left from the rip and the inside seam where to two pieces came together. It didn't even look so bad. But still the rubber is so old and brittle super care is advised putting this puppy back on. So I waited another 24 hours for it to really set up, and that it did. I then made ready for the install only this time I brought out to the van a tall pot of boiling water. I soaked the accordion portion in the water for about 5 minutes. It did wonders for its flexibility. I got it in without even swearing

Hooked up the remaining hoses and crank her over. As expected, it raced at about 2K RPMs, which is where is should have been after cranking the idle up so high. Reset idle and she runs perfect.

Not an answer for the part but can surly get you back on the road.

I also ordered in a couple of boots used for 4 runners. Not sure if they are even close but I will send them back in not. But maybe we can find one, there are tons in use, that can be modified to work.

So all is good here. Thanks for all the support.
