Dude just use the whole 2.5L valve covers it's easier and they're stronger than the 3L plastic ones (and you can avoid the BS jerry-rigging to fit the coil).
The IAC fits fine in top of the plastic UIM. You just have to do this:
You need to keep the Taurus Throttle Body, and in order to do this you need to swap the linkage(trhottle shaft) from the Taurus with your SVT linkage, spring, TPS, and cable bracket (you already have the cable having an SVT so I am omitting that obvious necessity). You will find that a slight grinding of the body of the Taurus TB body may be required to remove the oint at with the SVT linkage interferes with it, but it super-simple to fix. When you do the swap you will also end up noticing that the butterfly will need to be changed around in it's closed position so that it can rotate in the opposite direction to the normal operation of the Tuarus butterlfy (hence why you need to use the SVT TPS).
