There are probably better ways to do this, but here's what I wound up doing for the intake saddle:
The intake tube needed to be shortened to fit the car. The cut portion of the tube made for a handy mold, when combined with some old cereal boxes and lots of electrician's tape.
The two-part urethane rubber compound (16 oz kit of 75-60 is $15 at
Molding Rubbers) was about the consistency of epoxy resin (molasses) when first mixed together, so electrician's tape was needed to make a waterproof seal around the cardboard and tube mold.
Some 1/8" x 1/2" hardware store flat stock aluminum was bent so that it would be captured by the rubber. Holes were drilled in the middle of the aluminum, to help the rubber fully capture the aluminum (probably this wasn't necessary?)
Before pouring the compound into the mold, the mold was sprayed with mold release (Stoner Urethane mold release $10 at
Mold Releases). This made it very easy to remove the mold; it pretty much fell off the part once the tape was removed.
The tray was to capture any compound that leaked out (none did) and the popsicle sticks kept the tube from rolling over while the rubber cured.
The "ears" of the new mount can be either drilled and bolted to the cross tubes, or fastened with hose clamps, like in the pictures. The hose clamps might not look as good, but they do the job. The sides of the mount are high enough that the tube can't bounce out (the rear clam lid is in the way) and in any case, the tube is stiff enough even without a mount that it won't move too much. The mount just keeps it from falling over time, and reduces the stress on the silicone coupler at the throttle body.
