Indy,
I just went through the same enjoyable experience. If you don't have patience before you start, you will, hopefully, have it when you're done with this project. I, too, used the smaller size hose to fit inside the hose provided with the DRM ducts. Dmtnt has a post on this somewhere, I believe.
Denny,
Fitting to the oem ducts is the easiest part of this operation. I just sliced a one inch cut on either side of the inlet of the DRM duct where it meets the oem ducts and popped a rivet or two to hold them together, along with some duct tape to seal them up. The DRM duct is attached to the inner fender with a self-tapping screw that comes with the kit. Can't see it at the angle of Indy's pic, if it's in there already.
I have to say, as I was doing this project on one side, it made the other side that much easier.
Oh yeah, I also cobbled together a neat fix for the abs sensor mount using the original bracket/fastener. I cut away the vast majority of the original bracket leaving the fastener and one bolt hole. I then trimmed that down to fit in and bolt to the forward bolt that holds the spindle/duct assembly together. It fit nice and uses the original clip to hold the sensor connector in place.
