On my '95 Impreza, it works as follows. The clips are two-piece type. Pop up the visible heads with a screwdriver, taped up if desired, and then you can pull the sill out with the clips still in it. Doing it in a warm weather reduces the risk of breaking anything. The inward edge of the sill trim has a bent over lip that engages a channel piece stapled along the edge of the carpet.

The vanes on a stamped impeller are straight, but not radial. Not sure what the real engineering considerations are. One of the factors which limits the pump flow capacity is the onset of cavitation. Perhaps a non-shrouded impeller is more cavitation-resistant, but I haven't really looked into it. -

The aftermarket brand of OE supplier is Paraut. But no guarantee that it's made to exactly the same specifications as the factory unit. -
Current service manuals, starting around year 2000 or so, do specify 132 lb*ft of torque for the crankshaft bolt. However, the current part number for this bolt is different from the one for "old school", as I learned recently when a FSM page was posted on NASIOC. But indeed people say the old spec. is too low. So the mystery remains. I tightened the bolt to 90 lb*ft.

If you cannot find this fluid, or regular Mobil, in a re-labeled form, I believe you can use a different brand. That's what happened two times in the past when I had the fluid changed by a dealer shop. They'd just drain and refill with what they had. Different brands of the same type of fluid are supposed to mix with each other.

Their current specification is Dexron-VI, backward-compatible, and that's what they're licensing for the aftermarket. Mobil 1 is not yet on their list: http://www.gm.com/explore/technology/gmpowertrain/transmissions/DEXRON_VI_Service_Fill_Release_31MY07.doc This is similar to the change from ATF+3 to ATF+4 by Chrysler.

Recently I replaced one on a 1995, w/o dropping the Y. A socket that did work was a "heavy duty" offset type with a double-square 1/2" drive. You just need to put the socket and the breaker bar into the right position. The converter housing is stainless, so the sensor should come out without much struggle, especially after applying PB Blaster for a couple of days.

Lots of room for confusion here, to be sure, including the meaning of "genuine". I'm not saying you must order individual wires, just trying to explain the difference between wires from boxed sets and those installed at the factory. Maybe the reason they came up with those sets is that indeed it would be difficult to order the wires individually, and many would balk at the cost. But the boxed sets are simply re-labelled aftermarket parts. As you just found yourself, they are not identical to OE. I did order the wires by part number (which was the same for all four on my 1995 2.2l) and received wires identical to the original ones. To paraphrase George Orwell, all ignition wires are genuine, but some wires are more genuine than others.
