Yes they are oblong. There should be an arrow on the Rubber telling you which end points down. Aside from being oblong, the hole in the TAB is not centered so pay attention to the arrow indicator on the rubber. I believe the Meatier rubber faces down. Use bearing grease on the threads of the Bolts. They are working pretty hard. Press the old ones out toward the Center of the car. You should be able to see the taper on the old ones showing which way to push.

When replacing the Springs, I found it easier ( on the Passenger side) to take the small bracket off teh Caliper. It's the bracket that is meant to leverage a bar off of when installing the Brake Pins. It'll give you that extra room you need because the exhaust is there.
